Detailed Explanation for this Vulnerability Assessment

Paul Starzetz and Wojciech Purczynski of isec.pl href="http://isec.pl/vulnerabilities/isec-0014-mremap-unmap.txt">discovered 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 rights.
For the stable distribution (woody) this problem has been fixed in
version 2.4.17-0.020226.2.woody5 for mips and mipsel kernel images.
Other architectures will probably mentioned in a separate advisory or
are not affected (m68k).
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 for the mips and mipsel architectures.
This problem is also fixed in the upstream version of Linux 2.4.25 and
2.6.3.
We recommend that you upgrade your Linux kernel packages immediately.
