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.", "title": "Topic" }, { "category": "general", "text": "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.\n\nSecurity Fix(es):\n\n* 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)\n\n* Qemu: vga: OOB read access during display update (CVE-2017-13672)\n\n* Qemu: vga: reachable assert failure during display update (CVE-2017-13673)\n\n* Qemu: Slirp: use-after-free when sending response (CVE-2017-13711)\n\n* 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)\n\nFor 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.\n\nRed 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.
