Current issues, 1 word:
Pants!
Patch yourself people. This is bad!
If you can't patch, just down for now and ip block for what you can't down!

Think of the following:
pFsense (not 1.2.3, but 2.1 versions)!
Any ssl enabled Apache site compiled against Openssl libs.
Any mail server running IMAP or POP3 over SSL.
Any SSL based VPN.
There is exploit code out there.


To check your versions of procs:
Follow up by checking the date and time of the lib (and version if you can).
You are shooting for libcrypto 1.0.1g and a date of 4/7/14 (Monday) for Ubuntu stuff.
cat /proc/*/maps | grep -i libcrypto


Pyopenssl does "detect" this attack. You should see:
