   An update that fixes 7 vulnerabilities is now available.

Description:


   OpenSSL 0.9.8j 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-2015-1788: Malformed ECParameters could cause an infinite loop.
       * 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.
       * CVE-2015-1792: A CMS verification infinite loop when using an
         unknown hash function was fixed.
       * CVE-2015-1791: Fixed a race condition in NewSessionTicket creation.
       * CVE-2015-3216: Fixed a potential crash in ssleay_rand_bytes due to
         locking regression.
       * 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)
       * Added the ECC ciphersuites to the DEFAULT cipher class (bnc#879179)
