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.

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)
