Security update for openssl-1_0_0 SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:2965-1 Final 1 1 2018-10-01T14:02:03Z current 2018-10-01T14:02:03Z 2018-10-01T14:02:03Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for openssl-1_0_0 This update for openssl-1_0_0 to 1.0.2p fixes the following issues: These security issues were fixed: - Prevent One&Done side-channel attack on RSA that allowed physically near attackers to use EM emanations to recover information (bsc#1104789) - 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) - Make problematic ECDSA sign addition length-invariant - Add blinding to ECDSA and DSA signatures to protect against side channel attacks This non-security issue was fixed: - Add openssl(cli) Provide so the packages that require the openssl binary can require this instead of the new openssl meta package (bsc#1101470) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
