SUSE Security Update: Security update for openssl ______________________________________________________________________________ Announcement ID: SUSE-SU-2018:1887-2 Rating: moderate References: #1097158 #1097624 #1098592 Cross-References: CVE-2018-0732 Affected Products: SUSE Linux Enterprise Server 12-SP2-BCL ______________________________________________________________________________ An update that solves one vulnerability and has two fixes is now available. Description: This update for openssl fixes the following issues: - 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". Alternatively you can run the command listed for your product: - SUSE Linux Enterprise Server 12-SP2-BCL: zypper in -t patch SUSE-SLE-SERVER-12-SP2-BCL-2018-1276=1 Package List: - SUSE Linux Enterprise Server 12-SP2-BCL (noarch): openssl-doc-1.0.2j-60.30.1 - SUSE Linux Enterprise Server 12-SP2-BCL (x86_64): libopenssl-devel-1.0.2j-60.30.1 libopenssl1_0_0-1.0.2j-60.30.1 libopenssl1_0_0-32bit-1.0.2j-60.30.1 libopenssl1_0_0-debuginfo-1.0.2j-60.30.1 libopenssl1_0_0-debuginfo-32bit-1.0.2j-60.30.1 libopenssl1_0_0-hmac-1.0.2j-60.30.1 libopenssl1_0_0-hmac-32bit-1.0.2j-60.30.1 openssl-1.0.2j-60.30.1 openssl-debuginfo-1.0.2j-60.30.1 openssl-debugsource-1.0.2j-60.30.1 References: https://www.suse.com/security/cve/CVE-2018-0732.html https://bugzilla.suse.com/1097158 https://bugzilla.suse.com/1097624 https://bugzilla.suse.com/1098592 _______________________________________________ sle-security-updates mailing list sle-security-updates@lists.suse.com http://lists.suse.com/mailman/listinfo/sle-security-updates |
