tricked into connecting to a malicious server, an attacker could
possibly exploit these to cause a denial of service via application
crash, potentially execute arbitrary code, or lead to information
disclosure.

This update also adds TLS v1.2 support to Ubuntu 10.04 LTS, Ubuntu
12.04 LTS, Ubuntu 12.10, and Ubuntu 13.04.
