{"id":"USN-2608-1","summary":"qemu, qemu-kvm vulnerabilities","details":"Jason Geffner discovered that QEMU incorrectly handled the virtual floppy\ndriver. This issue is known as VENOM. A malicious guest could use this\nissue to cause a denial of service, or possibly execute arbitrary code on\nthe host as the user running the QEMU process. In the default installation,\nwhen QEMU is used with libvirt, attackers would be isolated by the libvirt\nAppArmor profile. (CVE-2015-3456)\n\nDaniel P. Berrange discovered that QEMU incorrectly handled VNC websockets.\nA remote attacker could use this issue to cause QEMU to consume memory,\nresulting in a denial of service. This issue only affected Ubuntu 14.04\nLTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-1779)\n\nJan Beulich discovered that QEMU, when used with Xen, didn't properly\nrestrict access to PCI command registers. A malicious guest could use this\nissue to cause a denial of service. This issue only affected Ubuntu 14.04\nLTS and Ubuntu 14.10.
