An update that solves four 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-2015-1788: 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.

* 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.
