USN-2229-1: GnuTLS vulnerability

2 June 2014

GnuTLS could be made to crash or run programs if it connected to a malicious server.




Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello
messages. A malicious remote server or a machine-in-the-middle could use this
issue to cause GnuTLS to crash, resulting in a denial of service, or
possibly execute arbitrary code.

Update instructions

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

Ubuntu 14.04
Ubuntu 13.10
Ubuntu 12.04
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
