SuSE 10 Security Update : Xen (ZYPP Patch Number 7703)

This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

This update fixes various bugs in XEN :

The following security issues have been fixed :

- A denial of service (Host Crash) in the XEN hypervisor.

- A bug was found in the way Xen handles CPUID instruction
emulation during VM exits. An unprivileged guest user
can potentially use this flaw to crash the guest.

- A 64-bit guest can get one of its vcpus into non-kernel
mode without first providing a valid non-kernel
pagetable. The observed failure mode was usually a hard
lockup of the host (host denial of service).

It fixes also the following bugs :

- SLES 10 SP3 XEN: Device /dev/xvdp is already connected
error when starting multiple vm's. (bnc#654798)

- HVM taking too long to dump vmcore. (bnc#684297)
