Boss asked me about creating a rule for the OpenSSL Heartbleed.  I asked
him why not just go update all the servers.  He just stared at me.  So I am
submitting to the community for review and comment the rule I drew up on
this proof-of-concept exploit for the heartbleed vulnerability.

Exploit - https://gist.github.com/takeshixx/10107280
CVE - https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-0160

03 02 00 03 01 40 00 |"; reference:cve, CVE-2014-0160;)
