This update for gnutls fixes the following issues :
Security issue fixed :
CVE-2018-16868: Fixed Bleichenbacher-like side channel leakage in PKCS#1 v1.5 verification (bsc#1118087).
Non-security issue fixed: Explicitly require libnettle 3.4.1 to prevent missing symbol errors (bsc#1134856).
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.
