Synopsis

The remote Red Hat host is missing a security update for rhev-hypervisor6.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:1375 advisory.

The rhev-hypervisor6 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 a fix for one security issue. This issue had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fix included in this update addresses the following CVE number:

CVE-2012-4423 (libvirt issue)

This update also fixes the following bug:

* A dependency issue was found between the rhev-hypervisor-tools and rhev-hypervisor6-tools packages. Every time a user with one of the -tools packages installed ran yum update, the -tools package they had installed was removed and the other one installed. Even though rhev-hypervisor-tools obsoleted rhev-hypervisor6-tools, this update includes an updated rhev-hypervisor6-tools package that corrects this issue. Note that the package does not have meaningful content, is only here to fix the dependency issue, and may be removed by a future update. (BZ#855391)

This update includes the ovirt-node build from RHBA-2012:1374:

https://rhn.redhat.com/errata/RHBA-2012-1374.html

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rhev-hypervisor6 package based on the guidance in RHSA-2012:1375.
