   An update that solves three vulnerabilities and has two
   fixes is now available.

Description:


   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:
   - Improve S/390 performance on IBM z196 and z13 (bsc#954256)
   - Add support for "ciphers" providing no encryption (bsc#937085)
