OpenSSL has released updates addressing multiple vulnerabilities, one of which allows a remote attacker to downgrade 
vulnerable TLS connections to 512-bit export-grade cryptography—an attack known as Logjam (CVE-2015-4000 [ 
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-4000 ]). Exploitation of some of these vulnerabilities could 
allow the attacker to read and modify data passed over the connection.

Updates available include:


  * OpenSSL 1.0.2b for 1.0.2 users 
  * OpenSSL 1.0.1n for 1.0.1 users 
  * OpenSSL 1.0.0s for 1.0.0d (and below) users 
  * OpenSSL 0.9.8zg for 0.9.8r (and below) users 

Users and administrators are encouraged to review the OpenSSL Security Advisory [ 
https://www.openssl.org/news/secadv_20150611.txt ] and apply the necessary updates.
