On the 26 ISC handler Rob posted a onliner that a major flaw exposed TLS traffic (CVE-2016-0701) where an attacker could decrypt and obtain information on traffic that you would deem secure. "More recently (in version 1.0.2) support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support." [2]

This serious vulnerability affects OpenSSL version 1.0.2 and should upgrade to version 1.0.2f. Version 1.0.1 is not affected because support for X9.42 style parameter has not been implemented. If you are upgrading from source code, the latest version can be downloaded here or check your Linux version for package update.
