Ive been real busy lately, but I have now taken the time to really investigate the Heartbleed bug for the Cisco ASA. Here is how you can know for sure IF your ASA is affected. Here is the versions of OpenSSL affected, according to the CVE site:
(1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do
not properly handle Heartbeat Extension packets, which allows remote
attackers to obtain sensitive information from process memory via
crafted packets that trigger a buffer over-read, as demonstrated by
reading private keys, related to d1_both.c and t1_lib.c, aka the
With that said, you find out your version of ASA. For example, if your ASA version is 8.4.5. Then go to Cisco's site at this location: http://www.cisco.com/c/en/us/td/docs/security/asa/roadmap/asaroadmap.html#wp54064
Find your version and click on that link. Then click on the "Open
Source License" link and search for 'openssl' and verify your version of
openssl. Some versions dont appear to report the openssl version. Not sure why.
