Ubuntu Update for gnutls26 USN-2121-1

Solution
Please Install the Updated Packages.
Insight
Suman Jana discovered that GnuTLS incorrectly handled version 1 intermediate certificates. This resulted in them being considered to be a valid CA certificate by default, which was contrary to documented behaviour.
Affected
