Xen Security Issue Patched
An anonymous reader sends in word of a privilege escalation security issue identified in the open source Xen hypervisor. Xen has issued a hotfix and urged all users to install it. The problem was disclosed by Secunia last week. A user of a guest domain with root privileges could execute arbitrary commands in domain 0 via specially crafted entries in grub.conf when the guest system is booted.
Xen and the art of powercycle maintenance.
Thank goodness this was fixed. No longer will we have to worry about bearded miscreants sneaking into Xen and shooting the place up!
