Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for gnutls fixes the following security issues :

- GnuTLS could have crashed when processing maliciously crafted OpenPGP certificates (GNUTLS-SA-2017-2, bsc#1018832, CVE-2017-5335, CVE-2017-5337, CVE-2017-5336)

- GnuTLS could have falsely accepted certificates when using OCSP (GNUTLS-SA-2016-3, bsc#999646, CVE-2016-7444)

- GnuTLS could have suffered from 100% CPU load DoS attacks by using SSL alert packets during the handshake (bsc#1005879, CVE-2016-8610)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
