This update for openssl fixes the following issues: 

Security fixes:
- CVE-2015-3194: The signature verification routines will crash with a
  NULL pointer dereference if presented with an ASN.1 signature using the
  RSA PSS algorithm and absent mask generation function parameter. Since
  these routines are used to verify certificate signature algorithms
  this can be used to crash any certificate verification operation and
  exploited in a DoS attack. Any application which performs certificate
  verification is vulnerable including OpenSSL clients and servers which
  enable client authentication. (bsc#957815)
- CVE-2015-3195: When presented with a malformed X509_ATTRIBUTE structure OpenSSL would leak
  memory. This structure is used by the PKCS#7 and CMS routines so any
  application which reads PKCS#7 or CMS data from untrusted sources is affected.
  SSL/TLS is not affected. (bsc#957812)
- CVE-2015-3196: If PSK identity hints are received by a multi-threaded client then
  the values were wrongly updated in the parent SSL_CTX structure. This could
  result in a race condition potentially leading to a double free of the
  identify hint data.  (bsc#957813)

Non security bugs fixed:
- Clear the error after setting non-fips mode (bsc#947104)
- Improve S/390 performance on IBM z196 and z13 (bsc#954256)
- Add support for "ciphers" providing no encryption (bsc#937085)
