Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Nikos Mavrogiannopoulos discovered that GnuTLS incorrectly handled
certificate verification functions. If a remote attacker were able to
perform a man-in-the-middle attack, this flaw could be exploited with
specially crafted certificates to view sensitive information.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected libgnutls26 package.
Risk factor :
Medium / CVSS Base Score : 5.8
