Ubuntu 14.04 LTS / 15.04 : spice vulnerability (USN-2736-1)
Medium Nessus Plugin ID 85873
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionFrediano Ziglio discovered that Spice incorrectly handled monitor configs. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libspice-server1 package.
