Several local root exploits have been discovered recently in the Linux
kernel.  This security advisory updates the ARM kernel for
Debian GNU/Linux.  The Common Vulnerabilities and Exposures project
identifies the following problems that are fixed with this update:
   An integer overflow in brk() system call (do_brk() function) for
   Linux allows a local attacker to gain root privileges.  Fixed
   upstream in Linux 2.4.23.
   Paul Starzetz discovered
   a flaw in bounds checking in mremap() in
   the Linux kernel (present in version 2.4.x and 2.6.x) which may
   allow a local attacker to gain root privileges.  Version 2.2 is not
   affected by this bug.  Fixed upstream in Linux 2.4.24.
   Paul Starzetz and Wojciech Purczynski of isec.pl <a
   href="http://isec.pl/vulnerabilities/isec-0014-mremap-unmap.txt">discovered</a> a
   critical security vulnerability in the memory management code of
   Linux inside the mremap(2) system call.  Due to missing function
   return value check of internal functions a local attacker can gain
   root privileges.  Fixed upstream in Linux 2.4.25 and 2.6.3.
For the stable distribution (woody) these problems have been fixed in
version 2.4.16-20040204 of lart, netwinder and riscpc image and in
version 20040204 of kernel-patch-2.4.16-arm.
Other architectures will probably be mentioned in a separate advisory or
are not affected (m68k).
For the unstable distribution (sid) these problems will be fixed soon.
We recommend that you upgrade your Linux kernel packages immediately.
