Synopsis:          Important: kernel security and bug fix update
Issue Date:        2012-10-16
CVE Numbers:       CVE-2012-3412
--

This update fixes the following security issue:

* A flaw was found in the way socket buffers (skb) requiring TSO (TCP
segment offloading) were handled by the sfc driver. If the skb did not fit
within the minimum-size of the transmission queue, the network card could
repeatedly reset itself. A remote attacker could use this flaw to cause a
denial of service. (CVE-2012-3412, Important)

This update also fixes several bugs.

The system must be rebooted for this update to take effect.
