Security update for openssl (moderate)

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)
