RHSA-2015:0998-01 -- Redhat qemu-kvm, qemu-guest-agent

KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm 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 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. Red Hat would like to thank Jason Geffner of CrowdStrike for reporting this issue. All qemu-kvm 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.
