If you are applying Slackware security updates, then you have nothing to worry about, this hole was patched two days ago in all supported versions of Slackware (which means, 13.0 and up).
Code:
Mon Mar 3 23:32:18 UTC 2014
n/gnutls-3.1.22-x86_64-1.txz: Upgraded.
Fixed a security issue where a specially crafted certificate could
bypass certificate validation checks.
