Package : linux-2.6
Vulnerability : privilege escalation/denial of service
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2009-4307 CVE-2011-1833 CVE-2011-4347 CVE-2012-0045
CVE-2012-1090 CVE-2012-1097

Several vulnerabilities have been discovered in the Linux kernel that may lead
to a denial of service or privilege escalation. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2009-4307

Nageswara R Sastry reported an issue in the ext4 filesystem. Local users
with the privileges to mount a filesystem can cause a denial of service
(BUG) by providing a s_log_groups_per_flex value greater than 31.

CVE-2011-1833

Vasiliy Kulikov of Openwall and Dan Rosenberg discovered an information
leak in the eCryptfs filesystem. Local users were able to mount arbitrary
directories.

CVE-2011-4347

Sasha Levin reported an issue in the device assignment functionality in
KVM. Local users with permission to access /dev/kvm could assign unused pci
devices to a guest and cause a denial of service (crash).

CVE-2012-0045

Stephan Barwolf reported an issue in KVM. Local users in a 32-bit guest
running on a 64-bit system can crash the guest with a syscall instruction.

CVE-2012-1090

CAI Qian reported an issue in the CIFS filesystem. A reference count leak
can occur during the lookup of special files, resulting in a denial of
service (oops) on umount.

CVE-2012-1097

H. Peter Anvin reported an issue in the regset infrastructure. Local users
can cause a denial of service (NULL pointer dereference) by triggering the
write methods of readonly regsets.

For the stable distribution (squeeze), this problem has been fixed in version
2.6.32-41squeeze2.

The following matrix lists additional source packages that were rebuilt for
compatibility with or to take advantage of this update:

Debian 6.0 (squeeze)
user-mode-linux 2.6.32-1um-4+41squeeze2

We recommend that you upgrade your linux-2.6 and user-mode-linux packages.
