- Known Affected Systems:
- Linux 1.2.8 using NCSA HTTPd 1.5a
-
- Description:
-
- The InterNetwork Operating Company has discovered a security hole
- related to Linux 1.2.8 and NCSA HTTPd 1.5a. In affected systems, the
- NCSA server, running as nobody/nogroup is able to access any files that are
- mode ?00 (readable only by owner).
-
- The security hole is known to occur through symbolic links as
- well as through aliases specified in the srm.conf file.
-
- It is known that through properly placed symbolic links, it is
- possible to obtain the shadow password file, user mail files, etc. This
- is extermely important for public Internet Service Providers that provide
- users with WWW space.
-
- This same security hole has been tested on BSDI 2.0.1, which does
- not appear to be affected. It has not yet been tested on other systems
- or with other http servers.
