Oracle Linux 5 : xen (ELSA-2007-0114)
Medium Nessus Plugin ID 67461
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2007:0114 :
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 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.
SolutionUpdate the affected xen packages.
