openSUSE Security Update : xen (xen-1239)

high Nessus Plugin ID 40844

Synopsis

The remote openSUSE host is missing a security update.

Description

xend did not properly enforce access control of the xenstore directory tree, therefore allowing guest VM's to write there. This could lead to security problems if other applications such as libvirt are not prepared for untrusted data in the xenstore directory (CVE-2008-4405).

Solution

Update the affected xen packages.
