We will be scheduling an important kernel security and bug fix update this weekend.

This would take place as far as possible during the off-peak hours. A reboot is required to complete the upgrade. The downtime should not exceed 30 minutes and it will be minimize as much as possible.


This update is scheduled as follows:

Date: 20 October 2012 (Saturday) to 22 October 2012 (Monday)

Time: Between 2AM and 8AM EST

Details of security fix update


* 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)
