Red Hat has released a new patch for OpenSSL which fixes some serious security vulnerabilities, particularly with SSL enabled websites. There’s currently an attack method that hackers are using on vulnerable systems called DROWN. You can read more about it here – https://drownattack.com/
I would suggest updating the OpenSSL package on your web servers, and disabling older and vulnerable SSL connection types (SSLv2 and SSLv3).
Recommended course of action:
• Update OpenSSL. Red Hat and CentOS 5 and 6 packages available as of March 1
• Check Apache, Nginx, and Postfix settings to ensure that SSLv2 and SSLv3 are disabled
