Detail
Problem Description: An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 6. 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 Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 6 - 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. Security Fix(es): * Quick emulator(Qemu) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement and therefore causes unbounded memory allocation on the host controlled by the guest. (CVE-2016-5403) Red Hat would like to thank hongzhenhao (Marvel Team) 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/): 1358359 - CVE-2016-5403 Qemu: virtio: unbounded memory allocation on host via guest leading to DoS |
