Package name kernel
Date December 1st, 2003
Advisory ID MDKSA-2003:110
Affected versions 9.0, 9.1, MNF8.2, CS2.1
Synopsis Updated kernel packages fix vulnerability

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 kernel version 2.4.22-21mdk
(provided in MDKA-2003:021).

MandrakeSoft encourages all users to upgrade their systems immediately.

To upgrade your kernel, please use the documentation available online:

Upgrade

To upgrade your kernel, view the kernel update instructions. Kernels cannot be upgraded via MandrivaUpdate.


Verification

Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command :

                rpm --checksig package.rpm

You can get the GPG public key of the Mandriva Security Team to verify the GPG signature of each RPM.
