Having tested a few servers I’m involved with, many of which are using old or very old versions of OpenSSL, I can’t say I’ve found many with the problem. You can test a server here: http://filippo.io/Heartbleed/ on a site recommended by Bruce Schneier.
So what’s going on? Does this affect very specific nearly-new releases. This story could turn out to be a serious but solvable problem, and a media panic. I recall spending most of 1999 doing interviews on how the “year 2000 bug” was going to be a damp squib, but it’s early days yet.
