"This update for compat-openssl098 fixes the following security 
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)

  - 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-2018-0739: Constructed ASN.1 types with a recursive
    definition (such as can be found in PKCS7) could
    eventually exceed the stack given malicious input with
    excessive recursion. This could have resulted in DoS
    (bsc#1087102).
