Scientific Linux Security Update : xen on SL5.x i386/x86_64

high Nessus Plugin ID 60261

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Detail :

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)

Solution

Update the affected xen, xen-devel and / or xen-libs packages.
