Xen PV vulnerability?
Hello guys,
Since we do not run any xen nodes, and only openvz - kindly check what I got below from PCsmart in regards to a vulnerability in the xen kernel ... just a heads up.
If you are not already aware, a vulnerability has recently been found which has the potential for a PV guest to escalate priviledges to the hypervisor.
If you are running on the standard Xen build included with CentOS5 / RHEL5, you can simply install the latest kernel with a "yum update" and you will be protected. However if you have a newer version of Xen installed which we typically do for performance reasons, you are vulnerable.
For customers on recurring management, please contact us and we will work with you to arrange a suitable time/date to carry out this work.
If we have done work for you recently and you would like to be upgraded, please also contact us and we will work something out.
We do have quite a few systems to get through, so your patience once you have submitted your ticket would be appreciated.
Many Thanks,
The PCSmart Team
