An update that solves one vulnerability and has two fixes
is now available.
Description:
This update for openssl 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)
This update was imported from the SUSE:SLE-12-SP2:Update update project.
