- 0.83
- ----
-
- Due to a high number of bad files produced by broken software, the MS05-002

-
- 0.81
- ----
-
- Scan engine improvements were made. The internal mail scanner now supports
- multipart/partial messages, and support for decoding non-standard mail files
- was greatly enhanced. clamav-milter by default uses libclamav and scans emails
- itself without the use of clamd. libclamav can now extract RFC2397 encoded
- data within HTML documents, block zip archives with modified information in
- local header, and scan HQX files. PE file structure rebuilding from compressed
- executables was improved.
-
- Important note to clamdwatch users: please upgrade to the latest version
- (contrib/clamdwatch) as soon as possible.
-
- -) libclamav:
- + major improvements in the mail scanning engine:
- o support for multipart/partial messages
- o improved support for non-standard quoted-printable attachments
- o in some situations it will try to guess a correct mode (e.g.
- a good type for an incorrect content-type, a best guess for an
- unknown encoding type, etc.)
- o handling of RFC822 comments in the commands (e.g.: Co(foo)ntent-Type:
- text/plain)
- o better recovery if memory softlimit is hit
- o new test code that decodes emails without parsing them first (must
- be enabled manually before compilation)
-
- + support for extracting RFC2397 encoded data within HTML documents
- + blocking of zip archives with modified information in local header
- + improved PE structure rebuilding from compressed executables
- + improved support for zip archives
- + support for Mac's HQX file format
- + stability and (minor) security fixes

- memory condition)
- + new directives StreamMinPort and StreamMaxPort (port range specification
- for a stream mode)
- + support for passing of file descriptors
-
- -) clamdscan:
- + added support for --move and --remove
-
- -) clamav-milter:
- + by default uses libclamav to scan e-mails
- + new option --external (enables the use of clamd)
- + various optimisations
-
- -) freshclam:
- + the DNS mode is now enabled by default (no need for DNSDatabaseInfo in
- freshclam.conf)
- + --no-dns uses a If-Modified-Since method instead of a range GET
- + added support for AllowSupplementaryGroups
-
- -) sigtool:
- + new options --vba and --vba-hex (extract VBA/Word6 macros and optionally
- display the corresponding hex values; Word6 binary code will be
- disassembled)

-
- Stable version. Please read the release notes for the candidate versions below.
-
- --
- The ClamAV team (http://www.clamav.net/team.html)
-
-
- 0.80rc4
- -------
-
- Improvements in this release include better JPEG exploit verification,
- faster base64 decoding, support for GNU tar files, updated on-access scanner,
- and others.

- The ClamAV team (http://www.clamav.net/team.html)
-
- 0.80rc3
- -------
-
- This release candidate eliminates possible false positive alerts in UPX/FSG
- compressed files and clarifies behaviour of default actions in clamd and
- freshclam.
-
- We encourage users to take advantage of our new mirror structure. In order to
- download the database from the closest mirror you should configure freshclam
- to use db.XY.clamav.net where XY is your country code (see
- http://www.iana.org/cctld/cctld-whois.htm for the full list). Please add
- the following lines to freshclam.conf:
-
- DNSDatabaseInfo current.cvd.clamav.net
- DatabaseMirror db.XY.clamav.net
- DatabaseMirror database.clamav.net
-
- DNSDatabaseInfo enables database and software version verification through
- DNS TXT records, and the second database mirror acts as a fallback in case
- a connection to the first mirror fails for some reason.
-
-
- 0.80rc2
- -------
-
- This update fixes a serious bug in e-mail scanner.
-
-
- 0.80rc
- ------
-
- The development version of ClamAV is ready for general testing! New mechanisms
- have already proved very nasty to Internet worms successfully protecting
- against the new versions R, S, T, U, V and W of the infamous Mydoom worm
- and detecting them as Worm.Mydoom.Gen before they were analysed and specific
- signatures added by the ClamAV database maintainers. That means servers running
- the new version of ClamAV have detected and blocked 100% of Mydoom attacks!

-
- -) sigtool
- + removed ability of automatic signature generation (use MD5 sums to
- create your own signatures, see signatures.pdf for details)

- Special thanks to aCaB for his work on UPX, FSG and Petite decompressors.
-
- Thanks to good reaction times on new threats ClamAV was awarded as best
- security tool for 2004 by Linux Journal: "...With this year's outbreak of
- e-mail worms for non-Linux platforms, ClamAV has been getting quite a workout,
- and Linux admins on mailing lists report that database update times are keeping
- up with or beating the proprietary alternatives." Thanks!

- 0.75
- ----
-
- This release fixes detection of e-mails generated by Worm.Mydoom.I.
-
- Important notice for people using ClamAV 0.60:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- Our logs show that there is still a small percentage of ClamAV 0.60
- installations updating their database. ClamAV 0.60 was released on
- July 29th, 2003 and it was the last release to use the old database
- format. Starting from version 0.65, released on November 12nd, ClamAV
- uses a new database format, which is compressed and digitally signed.
- We have been distributing the database in both formats till now, but
- we plan to drop support for ClamAV 0.60 on September 1st.
-
- We encourage _all_ users to upgrade to the latest release available.
- People running an old version of ClamAV are missing many viruses and
- may experience stability problems.
-
- On non-production systems you can try the latest development version.
- The new engine not only speeds up the scanning process but also limits
- memory usage by about 8 MB ! It's able to scan new formats, including
- CAB, CHM, UPX, HTML (normalisation), PowerPoint macros and can detect
- annoying e-mails with empty attachments generated by new Bagle variants.

-
-
- Thanks to the help of many companies (clamdoc.pdf: Section 2.10,
- http://www.clamav.net/mirrors.html) we have 49 very fast and reliable
- virus database mirrors in 22 regions and the number is still growing.
- As of March 2004 we attempt to redirect our users to the closest pool
- of mirrors by looking at their ip source address when they try to resolve
- database.clamav.net. Our DNS servers can answer with a CNAME to:
- db.europe.clamav.net, db.america.clamav.net, db.asia.clamav.net or
- db.other.clamav.net. Our advanced push-mirroring mechanism (maintained by
- Luca Gibelli) allows database maintainers to update all the mirrors in less
- than one minute !
-
-
- There will be no major feature enhancements in the 0.7x series. Our work
- will be concentrated on a new scanning engine and preliminary heuristics -
- please help us and test CVS snapshots from time to time.
-
-
- We are happy to announce new programs with support for ClamAV (all of them

- News:
-
- ClamAV was the first anti-virus protecting against Worm.SCO.A (aka MyDoom.A) !
- The signature was published by Diego d'Ambra in the daily update 105,
- 26-Jan-2004 20:23 GMT and we were at least two hours faster than "big" AV
- vendors:
- http://sourceforge.net/mailarchive/forum.php?thread_id=3764826&forum_id=34654
- http://www.pcwelt.de/news/viren_bugs/37278/4.html
-
-
- clamav-devel is finally able to decode OLE2 (Microsoft Office) files and
- decompress VBA streams ! The code is developed by Trog, official ClamAV
- developer. Also we're testing new clamd implementation that will solve
- several important problems (especially that "Time out" related). Please
- help us and test the latest CVS version.
-
-
- The virus database now contains more than 20.000 signatures ! On January 8,
- Denis De Messemacker (who joined our team 3 months ago) added signatures for
- about 7700 new viruses. Also special thanks go to Tomasz Papszun for his
- hard work on daily submissions and forcing us to keep ClamAV quality on
- the highest possible level.
-
-
- New mirroring mechanisms. Luca Gibelli (ClamAV) and mirror administrators
- (22 sites, http://www.clamav.net/mirrors.html, please see clamdoc.pdf for
- a complete mirror information) are converting mirrors to new "push mirroring"
- method. It uses advanced techniques to ensure all the mirrors are up to date.
- More info: http://www.clamav.net/docs/mirrors

- 0.60
- ----
-
- Hello again...
-
- This is a new, (very?) stable release of Clam AntiVirus. 0.60 was developed
- and stabilized for over seven months and many people had contributed to the
- final release. This version introduces many enhancements and a new program:
- clamav-milter written by ClamAV developer Nigel Horne. This is a mail scanner
- for Sendmail/milter written entirely in C, which uses clamd for virus scanning.
- Clamav-milter and clamd duet is a powerful solution for systems where high
- performance is required. Please check clamdoc for more detail.
-
-
- Many people get confused with ClamAV database status because of
- the OpenAntiVirus update information at:
- http://openantivirus.org/latest.php
- (last update at 17 October, 2002). The ClamAV virus database contains
- the OAV database (with some signatures fixed or removed) but we
- develop it independently of the OAV project. Our database is updated
- frequently (on average 4-5 times a week). You can help (or join) us -
- will find some basic but useful instructions at
- http://clamav.elektrapro.com/doc/signatures.pdf
-
-
- News from ClamAV world:
-
- -) New email address for virus submitting: virus@clamav.elektrapro.com
- You don't need to encrypt a virus sample, but if your system doesn't allow
- you to send infected files just put it into an encrypted zip archive
- (password: virus)
-
- Special thanks to Nicholas Chua, Diego D'Ambra, Hrvoje Habjanic, Nigel Kukard
- and Chris van Meerendonk for a big number of samples submitted.
-
- -) New mailing list: virusdb@clamav.elektrapro.com
- After each update an email with subject "[clamav-virusdb] Update" and a list
- of viruses added is sent to it. You can set up a procmail rule for freshclam
- to react on such a mails (and update the database just after an update).
-
- -) New official mirrors:
- + clamav.ozforces.com: database mirror updated manually (thanks to
- Andrew <andrew@ozforces.com>)
- + clamav.essentkabel.com: full (automatic) mirror of clamav.elektrapro.com
- (thanks to Chris van Meerendonk <cvm@castel.nl>)
- + clamav.linux-sxs.org: database mirror - rsync from clamav.ozforces.com
- (thanks to Douglas J Hunley <doug@hunley.homeip.net>)
-
- Freshclam will automatically use them when the main server is not
- accessible.
-
- -) Official port in FreeBSD available ! (maintained by Masahiro Teramoto
- <markun@onohara.to>)
-
- -) Unofficial port for OpenBSD is available at:
- http://www.activeintra.net/openbsd/article.php?id=5
- (maintained by Flinn Mueller <flinn@activeintra.net>)
-
- -) there are many new programs that use ClamAV, eg. mod_clamav (Apache
- virus scanning filter), clamdmail or Sagator. You will find more
- info in clamdoc.
-
- Changes:
-
- -) libclamav:
- + fixed buffer overflow in unrarlib (patch by Robbert Kouprie
- <robbert@exx.nl>)
-
- + various mbox code updates (fixed memory leak; added support for decoding
- viruses sent in message bodies, detection of viruses that put their
- payloads after the end of message marker (thanks to Stephen White
- <stephen@earth.li> for the bug report and useful CGI tools);
-
- + zziplib updated to 0.10.81 (some problems with older version were reported
- by Martin Schitter)
- + direct scanning of mbox/maildir files (new directive CL_MAIL)
- + file scanner optimization (patch by Hendrik Muhs
- <Hendrik.Muhs@student.uni-magdeburg.de>)
- + bzip2 support
- + faster detection of malformed Zip archives (eg. 'Zip of Death'), they are
- reported as a viruses
- + fixed strcasecmp() compile problem in zziplib on Free/NetBSD and others
-
-
- -) clamd:
- + fixed descriptor leak in directory scanner - it was causing random
- clamd crashes and locks, especially on highly loaded servers. Reported
- by Kristof Petr <Kristof.P@fce.vutbr.cz>.
-
- + fixed crash with archive scanning on BSD (increased thread stack size)
- (Nigel Horne)
- + fixed CONTSCAN command (used by clamdscan) - it had archive support
- disabled (hardcoded)
- + fixed SelfCheck option (there was a logic bug, and the option was
- disabled) it now checks a databases time stamps and reloads them
- if needed.
- + fixed possible writing to undefined descriptors (bug found by
- Brian May <bam@debian.org>)
- + new STREAM command (scanning data on socket) and directives:
- StreamSaveToDisk (save stream to disk to allow scanning within archives),
- StreamMaxLength. This option allows scanning data on socket (might be
- sent from another host), currently only clamav-milter uses this.
-
- + new ScanMail directive for scanning into mbox/Maildir files
- + new directive: ArchiveLimitMemoryUsage (limit memory usage with bzip2)
- + new directive: AllowSupplementaryGroups (feature requested by Exiscan
- users)
- + syslog support (LogSyslog) (patch by Hrvoje Habjanic
- <hrvoje.habjanic@zg.hinet.hr>)

- internal unpacker) (patch by Damien Curtain <damien@pagefault.org>)
- + --move option for moving infected files into a specified directory
- (by Damien Curtain <damien@pagefault.org>)
- + --mbox enables a direct support for mbox files
- (ex. clamscan --mbox /var/spool/mail)
- + fixed --log (-l) option
- + fixed -i option (patch by Magnus Ekdahl <magnus@debian.org>)
- + enabled default archive limits (max-files = 500, max-size = 10M,
- max-recursion = 5)
- + use arj instead of non-free unarj (patch by Magnus Ekdahl)
- + use unzoo instead of non-free zoo (patch by Magnus Ekdahl)
- + removed thread support
-
- freshclam:
- + mirror support (implemented by Damien Curtain <damien@pagefault.org>)
- + --proxy-user: proxy authorization support (implemented by Gernot Tenchio
- <g.tenchio@telco-tech.de>)
- + new options --on-error-execute, --on-update-execute
- (ex. freshclam -d -c 6 --on-error-execute "sendsms 23332243 Can't
- update virus database"). Idea by Douglas J Hunley <doug@hunley.homeip.net>
-
- configure:
- + --disable-cr (don't link with C reentrant library (needed on some newer
- versions of OpenBSD))
-
- -) Enhanced AIX (thanks to Mike Loewen <mloewen@sturgeon.cac.psu.edu>) and
- Tru64 support (thanks to Christophe Varoqui <ext.devoteam.varoqui@sncf.fr>)

- 0.54
- ----
- Many major changes this time...
-
- -) libclamav:
- + fixed segfault with some strange zip archives (there is a bug in zziplib,
- libclamav contains a work around for it) (the problem was reported by
- Oliver Paukstadt <pstadt@stud.fh-heilbronn.de>)
- + engine improvements (better support for a detection of new viruses,
- limited memory usage (consumes ~ 5 Mb now))
- + mbox code updated and moved into the library: fixed core dump when an
- embedded message includes a mime header with the line Content-Type:
- without specifying the type of content, fixed (theoretical) memory leak,
- support for multipart/report messages, fixed bug causing some formats to
- fail to scan) (Nigel)
- -) clamd:
- + new commands: CONTSCAN (it doesn't stop scanning even when virus is
- found), VERSION
- + disable logging of a unnecessary time stamps with LogTime when
- LogVerbose isn't used (patch by Ed Phillips <ed@UDel.Edu>)
- -) freshclam:
- + "Cache-Control: no-cache" enabled by default
- + Cygwin support fix
- -) clamdscan:
- + initial version
- -) all tools:
- + removed huge printf() in help() (there was a buffer overflow problem with
- --help option under Windows and SCO Unix (reported by Wojciech Noworyta
- <wnow@konarski.edu.pl> and Nigel respectively)
- -) configure:
- + allow configuration of the clamav user and group with --with-user and
- --with-group (patch by Patrick Bihan-Faou <patrick@mindstep.com>)
- + --enable-id-check - it uses the check procedure from Jason Englander
- <jason@englanders.cc>, currently it will fail on systems with getent
- which doesn't detect clamav group.
- + do not overwrite the existing config file
-
-
- There are initial packages for Windows available at:
- http://clamav.elektrapro.com/binary
-
- --tk
-
-
- 0.53
- ----
- This release has removed the limit for a file name length in clamscan. Some
- viruses (eg. W32/Yaha.E) are using very long file names, and they were
- ignored in mbox mode. Users of AMaViS-ng and other wrappers were not
- vulnerable to this problem, because that programs don't use original
- attachement file names.
-
- -) clamscan:
- + removed limit for a file name length (thanks to Odhiambo Washington
- <wash@wananchi.com> for the test files and extensive mbox testing)
- + mbox: adapted to the new changes, enabled thread support (Nigel),
- re-enabled temporary directory removing.
-
- 0.52
- ----
-
- This version contains a portability fixes - it should compile on OpenBSD,
- MacOSX and NetBSD (support for them was broken in 0.51).
-
- -) clamd: various fixes:
- + drop supplementary groups (suggested by Enrico Scholz
- <enrico.scholz@informatik.tu-chemnitz.de>) (this has been implemented
- in freshclam, too)
- + work-around for the segmentation fault at QUIT under FreeBSD
- + check timeouts when waiting for threads in RELOAD mode
- + SelfCheck - internal integrity check (by default every 1 hour)
- + fixed problem with directory scanning on non typical file systems
- (bug reported by Jason Englander <jason@englanders.cc>)
- + clamd is a system command (clamd.1 -> clamd.8, /usr/local/bin ->
- /usr/local/sbin) (Magnus Ekdahl)
- -) clamscan:
- + mbox code updates (Nigel Horne) - it fixes some problems on *BSD
- systems (see mailing lists archives for the details)
- + enable core dumping (Nigel Horne) [ with --enable-debug ]
- -) freshclam:
- + applied http-proxy patch from http://bugs.debian.org/clamav (by
- Martin Lesser <admin-debian@bettercom.de>)
- + when configured with --disable-cache, freshclam forces 'no-cache'
- option in proxy servers (patch by Ant La Porte <ant@dvere.net>)
-
- -) HPUX (10.20/11.0 tested) support (thanks to Joe Oaks <joe.oaks@hp.com>)
- -) fixed support for SCO Unix and BeOS (Nigel Horne)
- -) support/mboxscan: new version with SpamAssassin support (Nigel Horne)
- -) re-included TrashScan 0.08 (by Trashware <trashware@gmx.de>) - the security
- issue has been fixed.
- -) included "Installing qmail-scanner, Clam Antivirus and SpamAssassin under
- FreeBSD" how-to by Paul Hoadley and Eric Parsonage
-
-
- 0.51
- ----
-
- OAV database is up to date ! There was a problem with signature parsing,
- because some hex strings were upper case. Anyway, I still recommend you
- freshclam for a database updating.
-
- -) support for the genuine OAV database
- -) limited memory usage (at the cost of speed, increase CL_MIN_LENGTH in
- libclamav/clamav.h to make it faster, it's safe to set it on 3-4 for
- the OAV database)
- -) fixed compile problem on TurboLinux 6.5 (probably others, too), the bug
- was reported by Henk Kuipers <henk@opensourcesolutions.nl>.
- -) clamd: fixed THREXIT (thanks to Piotr Gackiewicz <gacek@intertele.pl>)
- -) clamd: fixed serious bug with thread argument type
- -) clamscan: mbox: don't scan empty attachments (Nigel Horne)
- -) configure: --with-db1, --with-db2 (suggested by Magnus Ekdahl)
-
-
- 0.50
- ----
-
- Here it is...
- Clam AntiVirus 0.50 contains an anti-virus library - libclamav, a fully
- multi-threaded daemon clamd(1) and a quite long list of changes. The
- documentation was rewritten and you _should_ review it. By courtesy of
- NERvOus <nervous@nervous.it> and ElektraPro, there are three mailing lists
- available - you can subscribe via www at http://clamav.elektrapro.com/ml.
- Please check the manual for more information.
-
-
- New software:
-
- -) libclamav with RAR, Zip and Gzip support built-in. The library is thread
- safe and should be very secure, also. It uses UniquE RAR File
- Library by Christian Scheurer and Johannes Winkelmann (RAR 2.0 support only)
- and zziplib library by Guido Draheim and Tomi Ollila. Both of them are
- included and slightly modified in the clamav sources. You need the zlib
- library for the Zip/Gzip support, though. The API is described with
- examples in the clamdoc.
-
- -) clamd: a modern anti-virus daemon. It uses configuration file clamav.conf
- described in the clamav.conf(5) manual. The program was written with
- security as a goal.
-
- -) clamuko: on-access scanning under Linux. It utilizes Dazuko kernel module
- (GPL, http://dazuko.org) and is clamd-based.
-
- New features / improvements:
-
- -) enhanced scanner engine (better detection of some complex polymorphic
- viruses)
-
- -) clamscan: Nigel Horne <njh@bandsman.co.uk> has added the ability to scan
- mail attachments in a filter. For example:
-
- $ clamscan -i --mbox - < /var/spool/mail/john
- /tmp/aa6b9fc06bc477ae/setup.exe: Worm/Klez.H FOUND
-
- Nigel is the author of the whole mbox code in clamscan. Currently it only
- works in a filter mode, but there are plans to move the code into the
- libclamav and allow clamd using it. Please check support/mboxscan, also.
-
- -) clamscan: support for including and excluding multiple patterns with
- --include and --exclude (patch by Alejandro Dubrovsky
- <s328940@student.uq.edu.au>).
- Example: clamscan --include .exe --include .obj --include .scr /mnt/windows
-
- -) clamscan: don't scan /proc files (Linux, st_dev comparing). No more
- /proc/kcore related mails :))
-
- -) clamscan: use libclamav's archive support by default (it's enabled by default
- and may be disabled with --disable-archive) and switch to the external
- unpackers (if specified) in the case of libclamav archive code error.
-
- -) freshclam: proxy support (via $http_proxy variable and --http-proxy).
- I started implementing proxy support some time ago, but never finished.
- Nigel Horne did the great job and has finished the proxy support !
-
- -) freshclam: --daemon-notify. freshclam will send the RELOAD command to the
- daemon after database update (supports both tcp and local sockets, it reads
- clamav.conf to determine the socket type).
-
- -) freshclam: support for viruses.db2
-
- Bug fixes:
-
- -) freshclam: log 'Database updated' message (thanks to Jeffrey Moskot
- <jef@math.miami.edu> for the bug report). It now prints a number
- of signatures in a database, also.
-
- -) clamscan: fixed compile problem on Solaris 8 and some other systems -
- #include <signal.h> lack in others.c (thanks Mike Loewen
- <mloewen@sturgeon.cac.psu.edu> for the bug report)
-
- Documentation:
-
- -) included Japanese documentation by Masaki Ogawa <proc@mac.com>
-
- -) updated Spanish "Sendmail + Amavis + ClamAv - Como" by Erick I. Lopez
- Carreon <elopezc@technitrade.com>
-
- -) rewritten clamdoc, included clamdoc-html, removed PostScript version (.ps)
-
- -) Clam-Mutant ;) logo update by Michal Hajduczenia <michalis@mat.uni.torun.pl>
-
- -) new man pages: clamd(1), clamav.conf(5); others updated
-
-
- !!!
- Please don't use the oav-update script with this version. It doesn't
- update viruses.db2 and supports OpenAntiVirus.org site only (the last
- update of the OAV database was 1 July !). Nicholas Chua <nicholas@ncmbox.net>
- has generated over 200 new signatures, ClamAV's database is also frequently
- updated (expecially when new wild virus/worm appears, eg. W32/BugBear.A).
-
- This software is still in developement (new software == new bugs), however
- clamscan should be very stable. You shouldn't use clamd/clamuko (well, clamd is
- stable, clamuko isn't) on production systems, yet. Please wait for 0.51 at
- least ;). ClamAV 0.50 was tested on Linux and Solaris and should work fine.
- There is a problem with clamd on FreeBSD (tested on my FreeBSD 5.0-CURRENT) -
- the daemon crashes with Zip/Gzip files (disabling ScanArchive should help).
-
- Enjoy !

- 0.24
- ----
-
- -) fixed threads deadlock in a critical error situation (bug found by David
- Sanchez <dsanchez@veloxia.com>)
- -) fixed sigtool bug (negative seeking)
- -) fixed potential clamscan segfault in the case of memory allocation error
- -) unpacker execution error is no longer treated as critical - a few programs
- (eg. Qmail-Scanner, TrashScan) have clamscan command hardcoded with all
- archive options turned on. Now, if unpacker can't be executed, raw file is
- scanned and scan process is continued.
- -) reverted to pthread.h detection
- -) TrashScan 0.07 (Trashware <trashware@gmx.net>)
- -) --exclude (regular expressions are not supported !)
- [ex: clamscan --exclude="/proc/kcore" /], but please use it with care.
- -) included html documentation
-
- IMPORTANT NOTE:
- ~~~~~~~~~~~~~~~
- You will probably have a problem with a default Qmail-Scanner (1.13 or newer)
- installation. You need to increase qmail-smtpd softlimit or disable it. You
- can force clamscan to use only half of the memory which it uses by default, too.
- Please change the following line in the clamscan/matcher.h file:
- #define MIN_LENGTH 5
- to:
- #define MIN_LENGTH 3
- and recompile the program. Unhappily, scanning may be a little slower in some
- cases, but it shouldn't be significant. Then you can safely set the qmail
- softlimit to 8 MB. I want to thank Doug Monroe <doug@planetconnect.com> for
- his contribution in the problem analysis.
- ---
-
- New ClamAV version is in a heavy development. It has currently built-in
- support for RAR, Zip, Gzip and tar. The daemon will support only built-in
- compression/archive support. Snapshot will be available for a few days.
-
- 0.23
- ----
-
- -) fixed compile problem on FreeBSD (thanks to Wieslaw Glod <wkg@x2.pl> and
- Ken McKittrick <klmac@usadatanet.com>)
- -) clamscan reads all .db files from data directory, so you can put your
- own databases there and they won't be overwrited by the updaters. viruses.db
- is still the main database file (if --database isn't used).
- -) --deb (debian binary packages scanning) by Magnus Ekdahl <magnus@debian.org>
- -) --remove option, but be careful with it !
- -) new clam logo ;) (GPL) by Michal Hajduczenia <michalis@mat.uni.torun.pl>.
- -) TrashScan 0.06 (by Trashware <trashware@gmx.net>) - a script for scanning
- mail with procmail. I recommend it. (support/trashscan)
- -) documentation updates
-
- 0.30 release will contain a daemon and an anti-virus library (with simple API),
- so you can use it directly in your projects. I want to build in zip and rar
- support, also.
-
- There are binary packages for AIX available. Please check the documentation.
-
- 0.22
- ----
-
- This release fixes bug with scanning archives in unaccessible directories with
- *superuser* priviledges (after dropping priviledges scanner wasn't able to
- access the archive, although the same archive was accessible), thanks
- for Sergei Pronin <sp@finndesign.fi> for the problem description. Now all
- archives unaccessible directly by the clamav user are copied (with a respect to
- --max-space) to the temporary directory. All old filesystem tricks were removed.
-
- Other fixes / improvements:
-
- -) better error handling, new error codes
- -) improved -i (--infected) option
- -) removed --strange-unzip option
- -) removed eicar test files and logos from the documentation due to the GPL
- (thanks for Magnus Ekdahl <magnus@debian.org>), ClamAV-Test-Signature is
- used instead
- -) removed Qmail-Scanner patch, ClamAV is supported by Q-S 1.13 (thanks guys!)
- -) code cleanups
-
-
- 0.21 Release
- ------------
-

- 0.20 Release
- ------------
-
- The most important change in this release is a new, linear pattern matching
- algorithm. You will find more informations about it in clamscan/matcher.c -
- in the sources and in clamdoc. Summary (since 0.15):
-
- New features:
-
- -) fast pattern matching algorithm
- -) sigtool utility, check `man sigtool` and clamdoc
- -) Linux: threads autodetection on various architectures
- (Magnus Ekdahl <magnus@debian.org>)
- -) -i, --infected: clamscan prints only infected files
- -) 'Data scanned' in summary, size in megabytes with 16 Kb precision
- -) configure: --with-dbdir sets the database location
- -) support/sigmake shell script by Dennis Leeuw <leeuw@stone-it.com>
- -) Spanish "Sendmail+Amavis+ClamAv installation how-to" by
- Erick I. Lopez Carreon <elopezc@technitrade.com>
-
- Updates:
-
- -) "Debian GNU/Linux Mail Server v. 0.2.0" by Dennis Leeuw <leeuw@stone-it.com>

- 0.15 Notes
- ----------
-
- This version contains minor bugfixes only, such as:
- -) multiple fixes in freshclam (it has problems, when one of the
- hosts wasn't accessible), there were logic flaws in the code
- -) fixed problem with password protected archives (unpackers were waiting
- for password)
-
- New features:
- -) OpenBSD support (thanks to Kamil Andrusz <wizz@mniam.net>)
- -) added support for amavisd, qmail-scanner (see ./support)
-
- There were no major bugs and I was very busy, that's why new version is
- released just today. In the next 2 months, clamav development will be much
- faster. Here are some of my plans:
-
- ~ 0.20 : New pattern-matching algorithm
- ~ 0.30 : clamlib; clamscan and the daemon based on it
-
- There is a new homepage:
-
- http://clamav.elektrapro.com
-
- Thanks to ElektraPro.com for sponsoring this site (it's very fast).
- Thanks to NERvOus <nervous@nervous.it>.
-
- If you are interested in current development versions, please check
- snapshots link.
-
- Resource usage limits in 0.14
- -----------------------------
-
- Two new features: --max-files, --max-space have been implemented. If you have
- enabled one of this options, clamscan monitors resource usage (number of
- created files and used space) and stops extractor when it has exceeded
- the limit. You should use these options to protect your machine against
- Denial of Service attacks. In the near future --max-levels (limit for
- recursive archives extracting) and --max-time (spent on checking/extracting
- files) will be implemented.
-
-
- FreeBSD: AMaViS compile problems
- --------------------------------
-
- Please check FAQ.
-
- !!! Strange signatures in VirusSignatures-2002.04.15.10.51.zip !!!
- ------------------------------------------------------------------
-
- Last version of signatures was ~90 kb, this version is ~474 kb.
- But I don't understand, why some signatures are mega-huge. When I decoded
- them, they looked like regular files. In CA they were removed from the
- database and I probably add them later, in normal sizes.
-
- Installation :
- --------------
-
- Please view documentation in ./docs. There are several formats - pdf, ps
- and plain latex, if you want to compile it yourself.
-
- You need GNU make (on Solaris you should have gmake).
- It was tested only with gcc 2.9x compilers.
