Title:RHSA-2007:0323: xen security update (Important)
Description:The Xen package contains the tools for managing the virtual machine monitor in Red Hat Enterprise Linux virtualization.

The following security flaws are fixed in the updated Xen package:

  • Joris van Rantwijk found a flaw in the Pygrub utility which is used as a boot loader for guest domains. A malicious local administrator of a guest domain could create a carefully crafted grub.conf file which would trigger the execution of arbitrary code outside of that domain. (CVE-2007-4993)

  • Tavis Ormandy discovered a heap overflow flaw during video-to-video copy operations in the Cirrus VGA extension code used in Xen. A malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain. (CVE-2007-1320)

  • Tavis Ormandy discovered insufficient input validation leading to a heap overflow in the Xen NE2000 network driver. If the driver is in use, a malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain. Xen does not use this driver by default. (CVE-2007-1321)

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