Test ID:1.3.6.1.4.1.25623.1.0.70661
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0051
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:0051.

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 heap overflow flaw was found in the way QEMU-KVM emulated the e1000
network interface card. A privileged guest user in a virtual machine whose
network interface is configured to use the e1000 emulated driver could use
this flaw to crash the host or, possibly, escalate their privileges on the
host. (CVE-2012-0029)

A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT
(Programmable Interval Timer) IRQs (interrupt requests) when there was no
virtual interrupt controller set up. A malicious user in the kvm group on
the host could force this situation to occur, resulting in the host
crashing. (CVE-2011-4622)

Red Hat would like to thank Nicolae Mogoreanu for reporting CVE-2012-0029.

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

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
