Mandriva Linux Security Advisory MDKSA-2007:047
http://www.mandriva.com/security/
_______________________________________________________________________

Package : kernel
Date : February 21, 2007
Affected: 2007.0
_______________________________________________________________________

Problem Description:

Some vulnerabilities were discovered and corrected in the Linux 2.6
kernel:

A double free vulnerability in the squashfs module could allow a local
user to cause a Denial of Service by mounting a crafted squashfs
filesystem (CVE-2006-5701).

The zlib_inflate function allows local users to cause a crash via a
malformed filesystem that uses zlib compression that triggers memory
corruption (CVE-2006-5823).

The key serial number collision avoidance code in the key_alloc_serial
function in kernels 2.6.9 up to 2.6.20 allows local users to cause a
crash via vectors thatr trigger a null dereference (CVE-2007-0006).

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels immediately
and reboot to effect the fixes.

In addition to these security fixes, other fixes have been included
such as:

- New drivers: nozomi, UVC
- Fixed SiS SATA support for chips on 966/968 bridges
- Fixed issues in squashfs by updating to 3.2 (#27008)
- Added support for SiS968 bridgest to the sis190 bridge
- Fixed JMicron cable detection
- Added /proc/config.gz support and enabled kexec on x86_64
- Other minor fixes
