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

Description:


   OpenSSL was updated to fix several security issues.

       * CVE-2015-4000: The Logjam Attack ( weakdh.org ) has been addressed
         by rejecting connections with DH parameters shorter than 1024 bits.
         We now also generate 2048-bit DH parameters by default.
       * CVE-2015-1789: An out-of-bounds read in X509_cmp_time was fixed.
       * CVE-2015-1790: A PKCS7 decoder crash with missing EnvelopedContent
         was fixed.
       * fixed a timing side channel in RSA decryption (bnc#929678)

   Additional changes:

       * In the default SSL cipher string EXPORT ciphers are now disabled.
         This will only get active if applications get rebuilt and actually
         use this string. (bnc#931698)

   Security Issues:

       * CVE-2015-1789
         
       * CVE-2015-1790
