CVEs (cve.mitre.org): CVE-2015-3456

Details

Updated qemu-kvm-rhev packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 4.0, Red Hat
Enterprise Linux OpenStack Platform 5.0 for Red Hat Enterprise Linux 6 and
7, and Red Hat Enterprise Linux OpenStack Platform 6.0.

Red Hat Product Security 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.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the
user-space component for running virtual machines using KVM in environments
managed by Red Hat Enterprise Linux OpenStack Platform.

An out-of-bounds memory access flaw was found in the way QEMU's virtual
Floppy Disk Controller (FDC) handled FIFO buffer access while processing
certain FDC commands. A privileged guest user could use this flaw to crash
the guest or, potentially, execute arbitrary code on the host with the
privileges of the host's QEMU process corresponding to the guest.
(CVE-2015-3456)

Red Hat would like to thank Jason Geffner of CrowdStrike for reporting
this issue.

All qemu-kvm-rhev users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After installing
this update, shut down all running virtual machines. Once all virtual
machines have shut down, start them again for this update to take effect.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
