Red Hat Security Advisory
Synopsis: Moderate: rhev-hypervisor security and bug fix update
Advisory ID: RHSA-2011:0439-01
Product: Red Hat Enterprise Virtualization
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0439.html
Issue date: 2011-04-13
CVE Names: CVE-2011-1478
=====================================================================
1. Summary:
An updated rhev-hypervisor package that fixes one security issue and one
bug is now available.
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.
2. Relevant releases/architectures:
RHEV Hypervisor for RHEL-5 - noarch
3. Description:
The rhev-hypervisor 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 NULL pointer dereference flaw was found in the Generic Receive Offload
(GRO) functionality in the Linux kernel's networking implementation. If
both GRO and promiscuous mode were enabled on an interface in a virtual LAN
(VLAN), it could result in a denial of service when a malformed VLAN frame
is received on that interface. (CVE-2011-1478)
Red Hat would like to thank Ryan Sweat for reporting CVE-2011-1478.
This updated package provides updated components that include fixes for
security issues; however, these issues have no security impact for Red Hat
Enterprise Virtualization Hypervisor. These fixes are for dbus issue
CVE-2010-4352; kernel issues CVE-2010-4346, CVE-2011-0521, CVE-2011-0710,
CVE-2011-1010, and CVE-2011-1090; libvirt issue CVE-2011-1146; and openldap
issue CVE-2011-1024.
This update also fixes the following bug:
* Previously, network drivers that had Large Receive Offload (LRO) enabled
by default caused the system to run slow when using software bridging. With
this update, Red Hat Enterprise Virtualization Hypervisor disables LRO as a
part of a modprobe configuration. (BZ#692864)
Also in this erratum, the rhev-hypervisor-pxe RPM has been dropped.
As Red Hat Enterprise Virtualization Hypervisor includes Red Hat Enterprise
Virtualization Manager Agent (VDSM), the bug fixes from the VDSM update
RHBA-2011:0424 have been included in this update:
https://rhn.redhat.com/errata/RHBA-2011-0424.html
Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which resolves these issues.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
