Debian DSA-413-2 : linux-kernel-2.4.18 - missing boundary check

high Nessus Plugin ID 15250

Synopsis

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

Description

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, since it doesn't support the MREMAP_FIXED flag (as clarified later).

Solution

Upgrade the kernel packages. This problem has been fixed in the upstream version 2.4.24 as well.

For the stable distribution (woody) this problem has been fixed in kernel-source version 2.4.18-14.1 and kernel-images versions 2.4.18-12.1 and 2.4.18-5woody6 (bf) for the i386 architecture.
