Ubuntu 14.04 LTS : Spice vulnerability (USN-2736-1)

critical Nessus Plugin ID 85873

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2736-1 advisory.

 Frediano 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libspice-server-dev, libspice-server1 and / or spice-client packages.
