Between Tuesday, May 28 and Thursday, May 30, the Sipylus team will be performing a reboot of our environment. The nature of this reboot is to finalize the application of the latest, patched kernel to address a critical security issue.
On most host nodes, Sipylus anticipate less than 10 minutes of downtime, and they will make every effort to minimize the impact this will have on our service. Due to the critical nature of this vulnerability and the requirement of expediency, we can not reschedule this maintenance window, nor can we provide a more precise reboot time.
This update contains fixes for the following security issue:
A flaw was found in the way perf array index was sanitized. A local unprivileged user can use this flaw to increase their privileges on the system.
