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)");
