   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)
