Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated rhev-hypervisor5 package that fixes one security issue and
various bugs is now available.

The Red Hat Security Response Team has rated this update as having
important 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.

The rhev-hypervisor5 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: A subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

A flaw was found in the way socket buffers (skb) requiring TSO (TCP
segment offloading) were handled by the sfc driver. If the skb did not
fit within the minimum-size of the transmission queue, the network
card could repeatedly reset itself. A remote attacker could use this
flaw to cause a denial of service. (CVE-2012-3412)

Red Hat would like to thank Ben Hutchings of Solarflare (tm) for
reporting this issue.

This updated package provides updated components that include fixes
for various security issues. These issues have no security impact on
Red Hat Enterprise Virtualization Hypervisor itself, however. The
security fixes included in this update address the following CVE
numbers :

CVE-2012-4244 (bind issue)

CVE-2012-2319, CVE-2012-3430, and CVE-2012-3510 (kernel issues)

CVE-2011-3102, CVE-2012-0841, and CVE-2012-2807 (libxml2 issues)

Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which fixes these issues.
