Red Hat Security Advisory
Synopsis: Important: xen security update
Advisory ID: RHSA-2007:0114-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0114.html
Issue date: 2007-03-14
Updated on: 2007-03-14
Product: Red Hat Enterprise Linux
Keywords: xen qemu console ia64 VTi
CVE Names: CVE-2007-0998
- ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Multi OS (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, x86_64
RHEL Virtualization (v. 5 server) - i386, ia64, x86_64
3. Problem description:
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 initialization.
* 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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
