New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

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.
