Summary: An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 9.0 (Mitaka). Red Hat Product Security has rated this update as having a security impact of Important. 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 9.0 - x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. Security Fix(es): * Quick Emulator (QEMU), built with the Cirrus CLGD 54xx VGA Emulator and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603) 4. Solution: For details on how to apply thisupdate, 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.
