"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
    Jerome Marchand reported an issue in the futex subsystem
    that allows a local user to force an invalid futex state
    which results in a denial of service (oops).

This update also includes fixes for regressions introduced by previous
updates. See the referenced Debian bug pages for details."
