Security update for openssl-1_1 SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:2036-1 Final 1 1 2018-07-23T08:40:32Z current 2018-07-23T08:40:32Z 2018-07-23T08:40:32Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for openssl-1_1 This update for openssl-1_1 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) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
