-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: qemu-kvm-rhev security and bug fix update Advisory ID: RHSA-2018:1113-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:1113 Issue date: 2018-04-11 CVE Names: CVE-2017-13672 CVE-2017-13673 CVE-2017-13711 CVE-2017-15119 CVE-2017-15124 ===================================================================== 1. Summary: An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton), Red Hat OpenStack Platform 11.0 (Ocata), Red Hat OpenStack Platform 12.0 (Pike), Red Hat OpenStack Platform 8.0 (Liberty), and Red Hat OpenStack Platform 9.0 (Mitaka). 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 10.0 - x86_64 Red Hat OpenStack Platform 11.0 - x86_64 Red Hat OpenStack Platform 12.0 - ppc64le, x86_64 Red Hat OpenStack Platform 8.0 (Liberty) - x86_64 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): * The Network Block Device (NBD) server in Quick Emulator (QEMU), is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS. (CVE-2017-15119) * Qemu: vga: OOB read access during display update (CVE-2017-13672) * Qemu: vga: reachable assert failure during display update (CVE-2017-13673) * Qemu: Slirp: use-after-free when sending response (CVE-2017-13711) * VNC server implementation in Quick Emulator (QEMU) was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host. (CVE-2017-15124) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank David Buchanan for reporting CVE-2017-13672 and CVE-2017-13673 and Wjjzhang (Tencent.com) for reporting CVE-2017-13711. The CVE-2017-15119 issue was discovered by Eric Blake (Red Hat) and the CVE-2017-15124 issue was discovered by Daniel Berrange (Red Hat). 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.
