An update that solves one vulnerability and has two security fixes can now be installed.

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)
