Mandrake Linux Advisory: kernel

Dec 02, 2003, 02:56 (0 Talkback[s])

Mandrake Linux Security Update Advisory


Package name: kernel
Advisory ID: MDKSA-2003:110
Date: December 1st, 2003
Affected versions: 9.0, 9.1, Corporate Server 2.1, Multi Network Firewall 8.2

Problem Description:

A vulnerability was discovered in the Linux kernel versions 2.4.22 and previous. A flaw in bounds checking in the do_brk() function can allow a local attacker to gain root privileges. This vulnerability is known to be exploitable; an exploit is in the wild at this time.

The Mandrake Linux 9.2 kernels are not vulnerable to this problem as the fix for it is already present in those kernels.

MandrakeSoft encourages all users to upgrade their systems immediately.
