Updated qemu-kvm-rhev packages that fix one security issue are nowavailable for Red Hat Enterprise Linux OpenStack Platform 4.0, Red HatEnterprise Linux OpenStack Platform 5.0 for Red Hat Enterprise Linux 6 and7, and Red Hat Enterprise Linux OpenStack Platform 6.0.Red Hat Product Security has rated this update as having Important securityimpact. A Common Vulnerability Scoring System (CVSS) base score, whichgives a detailed severity rating, is available from the CVE link in theReferences section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution forLinux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides theuser-space component for running virtual machines using KVM in environmentsmanaged by Red Hat Enterprise Linux OpenStack Platform.An out-of-bounds memory access flaw was found in the way QEMU’s virtualFloppy Disk Controller (FDC) handled FIFO buffer access while processingcertain FDC commands. A privileged guest user could use this flaw to crashthe guest or, potentially, execute arbitrary code on the host with theprivileges of the host’s QEMU process corresponding to the guest.(CVE-2015-3456)Red Hat would like to thank Jason Geffner of CrowdStrike for reportingthis issue.All qemu-kvm-rhev users are advised to upgrade to these updated packages,which contain a backported patch to correct this issue. After installingthis update, shut down all running virtual machines. Once all virtualmachines have shut down, start them again for this update to take effect.
Before applying this update, make sure all previously released erratarelevant to your system have been applied.For details on how to apply this update, refer to:https://access.redhat.com/articles/11258Red Hat OpenStack 4.0
