Several local root exploits have been discovered recently in the Linux
kernel.  This security advisory updates the mips kernel 2.4.19 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 <a
   href="http://isec.pl/vulnerabilities/isec-0013-mremap.txt">discovered</a>
   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 2.4.19-0.020911.1.woody3 of mips images and version
2.4.19-4.woody1 of kernel source.
For the unstable distribution (sid) this problem will be fixed soon
with the next upload of a 2.4.19 kernel image and in version
2.4.22-0.030928.3 for 2.4.22.
We recommend that you upgrade your Linux kernel packages immediately.
