Summary: An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 8.0 (Liberty). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat OpenStack Platform 8.0 (Liberty) - x86_64 3. Description: 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 Virtualization Manager. The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386383) Security Fix(es): * An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818) Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 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. 5. Bugs fixed (https://bugzilla.redhat.com/): 1300771 - CVE-2015-8817 CVE-2015-8818 Qemu: OOB access in address_space_rw leads to segmentation fault 1374366 - RHSA-2016-1756 breaks migration of instances [OSP8] 1386383 - Rebase qemu-kvm-rhev to 2.6.0 6.
