Debian DSA-441-1 : linux-kernel-2.4.17-mips+mipsel - missing function return value check

high Nessus Plugin ID 15278

Synopsis

The remote Debian host is missing a security-related update.

Description

Paul Starzetz and Wojciech Purczynski of isec.pl 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 privileges.

Solution

Upgrade the Linux kernel packages immediately.

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).

This problem is also fixed in the upstream version of Linux 2.4.25 and 2.6.3.
