OpenSSL bug CVE-2014-0160 affects way more programs than just Tor.....POC Included

A new OpenSSL vulnerability on 1.0.1 through 1.0.1f is out today, which can be used to reveal up to 64kB of memory to a connected client or server.
If you're using an older OpenSSL version, you're safe.
Note that this bug affects way more programs than just Tor — expect everybody who runs an https webserver to be scrambling today. If you need strong anonymity or privacy on the Internet, you might want to stay away from the Internet entirely for the next few days while things settle.
