Package name kernel
Date January 2nd, 2007
Advisory ID MDKSA-2007:002
Affected versions 2007.0
Synopsis Updated kernel packages fix multiple vulnerabilities and bugs

Problem Description

Some vulnerabilities were discovered and corrected in the Linux 2.6

The Linux kernel does not properly save or restore EFLAGS during a
context switch, or reset the flags when creating new threads, which
could allow a local user to cause a Denial of Service (process crash)

The seqfile handling in the 2.6 kernel up to 2.6.18 allows local users
to cause a DoS (hang or oops) via unspecified manipulations that
trigger an infinite loop while searching for flowlabels

An integer overflow in the 2.6 kernel prior to could allow a
local user to execute arbitrary code via a large maxnum value in an
ioctl request (CVE-2006-5751).

A race condition in the ISO9660 filesystem handling could allow a local
user to cause a DoS (infinite loop) by mounting a crafted ISO9660
filesystem containing malformed data structures (CVE-2006-5757).

A vulnerability in the bluetooth support could allow for overwriting
internal CMTP and CAPI data structures via malformed packets

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:

- added the marvell IDE driver - use a specific driver Jmicron chipsets
rather than using a generic one - updated the sky2 driver to fix some
network hang issues

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


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.
