Affected Products:
                    SUSE Linux Enterprise Server for SAP 11-SP4

   An update that solves two vulnerabilities and has one
   errata is now available.


   This update for compat-openssl097g fixes the following issues:

   These security issues were fixed:

   - 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)
   - 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)

   This non-security issue was fixed:

   - Fixed crash in DES_fcrypt (bsc#1065363)
