SUSE SLES15 Security Update : openssl-1_0_0 (SUSE-SU-2018:2965-1)
Medium Nessus Plugin ID 120115
SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis 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
The update package also includes non-security fixes. See advisory for details.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
