spice vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 15.10
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Spice.

Software Description:
- spice: SPICE protocol client and server library

Details:

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
libspice-server1 0.12.6-4ubuntu0.1

Ubuntu 15.10:
libspice-server1 0.12.5-1.1ubuntu2.1

Ubuntu 14.04 LTS:
libspice-server1 0.12.4-0nocelt2ubuntu1.3

After a standard system update you need to restart qemu guests to make
all the necessary changes.
