This update for openssl-100 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)
