RHEL 5 : xen (RHSA-2007:0114)

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated Xen package to fix one security issue and two bugs is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The Xen package contains the tools for managing the virtual machine
monitor in Red Hat Enterprise Linux virtualization.

A flaw was found affecting the VNC server code in QEMU. On a
fullyvirtualized guest VM, where qemu monitor mode is enabled, a user
who had access to the VNC server could gain the ability to read
arbitrary files as root in the host filesystem. (CVE-2007-0998)

In addition to disabling qemu monitor mode, the following bugs were
also fixed :

* Fix IA64 fully virtualized (VTi) shadow page table mode

* Fix network bonding in balanced-rr mode. Without this update, a
network path loss could result in packet loss.

Users of Xen should update to these erratum packages containing
backported patches which correct these issues.
