Summary: Updated qemu-kvm-rhev packages that fix one security issue are now available for Red Hat Enterprise Virtualization. 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. 2. Relevant releases/architectures: RHEV Agents (vdsm) - 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. An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) Red Hat would like to thank Donghai Zhu of Alibaba 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5.

Summary: Updated qemu-kvm-rhev packages that fix two security issues and three bugs are now available for Red Hat Enterprise Virtualization. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEV Power Host - ppc64le RHEV-H and VDSM for 7 Hosts - 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. A use-after-free flaw was found in the way QEMU's IDE AHCI emulator processed certain AHCI Native Command Queuing (NCQ) AIO commands. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1568) An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) Red Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting the CVE-2016-1714 issue. This update also fixes the following bugs: * Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs. (BZ#1299345) * Previously, rebooting a guest after multiple memory hot-plugs in some cases caused the qemu-kvm process to terminate unexpectedly, and the reboot to fail. This update fixes the problem, and guests with hot-plugged memory reboot successfully. (BZ#1288096) * When the OHCI driver received an interrupt during the suspending process, the interrupt was not acknowledged. As a consequence, the interrupt kept being sent repeatedly, and the system became unresponsive. This update modifies the suspend procedure to acknowledge the interrupt, which prevents the described problem. (BZ#1298971) All qemu-kvm-rhev users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 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. 4.
