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.
