"This update for openssl fixes the following issues :

Security issues fixed :

CVE-2018-0734: Fixed timing vulnerability in DSA signature generation
(bsc#1113652).

CVE-2018-5407: Fixed elliptic curve scalar multiplication timing
attack defenses (bsc#1113534).

CVE-2018-0737: Corrected the current error detection of the current
fix (bsc#1106197).

CVE-2016-8610: Adjusted current fix and add missing error string
(bsc#1110018).

Add missing timing side channel patch for DSA signature generation
(bsc#1113742).

Fixed the 'One and Done' side-channel attack on RSA (bsc#1104789).

Non-security issues fixed: Added openssl(cli) so that the packages
that required the openssl binary can require this instead of the new
openssl meta package (bsc#1101470).

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."
