Debian: DSA-2012-1 Critical: Linux 2.6.26 Privilege Escalation

Two 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-2009-3725

Philipp Reisner reported an issue in the connector subsystem
which allows unprivileged users to send netlink packets. This
allows local users to manipulate settings for uvesafb devices
which are normally reserved for privileged users.

CVE-2010-0622

Jermome Marchand reported an issue in the futex subsystem that

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