available for Red Hat Enterprise Virtualization Hypervisor 7.
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.
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.
