Relevant releases/architectures: Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - x86_64 Red Hat Enterprise Linux OpenStack Platform 6.0 for RHEL 7 - x86_64 Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - 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 heap-based buffer overflow issue was found in the QEMU emulator's VNC display driver. It could occur while refreshing the VNC server's display surface using the vnc_refresh_server_surface() routine. A privileged guest user could use this flaw to corrupt the heap memory and crash the QEMU process instance, or to potentially use it to execute arbitrary code on the host. (CVE-2015-5225) Red Hat would like to thank Mr Qinghao Tang from QIHU 360 Inc. and Mr Zuozhi from Alibaba Inc. 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. After 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.
