openSUSE Security Update: Security update for openssl-1_0_0 ______________________________________________________________________________ Announcement ID: openSUSE-SU-2018:3015-1 Rating: moderate References: #1089039 #1097158 #1101470 #1104789 #1106197 Cross-References: CVE-2018-0732 CVE-2018-0737 Affected Products: openSUSE Leap 15.0 ______________________________________________________________________________ An update that solves two vulnerabilities and has three fixes is now available. Description: 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) This update was imported from the SUSE:SLE-15:Update update project.
