Linux Security Reboot

Tstaff will be performing a department-wide reboot of Linux desktop machines at 5:30am tomorrow, Wednesday, January 20th, to apply an urgent security patch. Please be sure to log out of your machines before then.

A major vulnerability was announced today in versions 3.8 and higher of the Linux kernel. The details may be found here:

Debian 8 "Jessie", which is what most of our desktop machines are currently running, uses the Linux 3.16 kernel. The announcement of the Debian patch is here: Machines running Debian 7 "Wheezy" are not affected, as they use Linux 3.2.

We will follow up on an individual basis with owners of VMs that are running Debian 8 "Jessie" to schedule reboots.

As always, please email with any questions or concerns.
