Details

Nikos Mavrogiannopoulos discovered that GnuTLS incorrectly handled
certificate verification functions. If a remote attacker were able to
perform a machine-in-the-middle attack, this flaw could be exploited with
specially crafted certificates to view sensitive information.

Update instructions

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

Ubuntu 13.10
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 10.04

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