SUSE Security Update: Security update for openssl1 ______________________________________________________________________________ Announcement ID: SUSE-SU-2018:2545-1 Rating: moderate References: #1089039 #1097158 #1097624 #1098592 Cross-References: CVE-2018-0732 CVE-2018-0737 Affected Products: SUSE Linux Enterprise Server 11-SECURITY ______________________________________________________________________________ An update that solves two vulnerabilities and has two fixes is now available. Description: This update for openssl1 fixes the following security issues: - CVE-2018-0737: The RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could have recovered the private key (bsc#1089039) - CVE-2018-0732: During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server could have sent a very large prime value to the client. This caused the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack (bsc#1097158) - Blinding enhancements for ECDSA and DSA (bsc#1097624, bsc#1098592) Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
