Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

Jing Zhao discovered that the Spice smartcard support incorrectly handled memory. A remote attacker could use this issue to cause Spice to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 15.10 and Ubuntu 16.04 LTS. (CVE-2016-0749)

Frediano Ziglio discovered that Spice incorrectly handled certain primary surface parameters. A malicious guest operating system could potentially exploit this issue to escape virtualization.
(CVE-2016-2150).

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.

Solution

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