Description :

From Red Hat Security Advisory 2010:0898 :

Updated kvm packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module
built for the standard Red Hat Enterprise Linux kernel.

A flaw was found in the way QEMU-KVM handled the reloading of fs and
gs segment registers when they had invalid selectors. A privileged
host user with access to '/dev/kvm' could use this flaw to crash the
host (denial of service). (CVE-2010-3698)

All KVM users should upgrade to these updated packages, which contain
a backported patch to correct this issue. Note: The procedure in the
Solution section must be performed before this update will take
effect.
