User blog comment:Powerhouse411/Word of Advice - Change Your Passwords/@comment-3387274-20140409190329

ok, in brief, as far as I can tell, one of the most commonly used tools for handling encrypted data via the internet has a flaw that has been found and possibly exploited. Which means just about anything that uses that tool (which is way too many things) is insecure and can have information stolen from it without a trace.

Changing passwords is definately advisable, but if they can be stolen now they can still be stolen until the patched version is implemented (so you may need to swap them out again later). I can't tell from the information here how long the vulnerability will last, I think service providers will try and send anouncments about it. In the meentime, I can only recomend being paranoid with just about anything sensetive.
