Ladies and gentlemen... Start your scanners

There a bug in OpenSSL 1.0.1 up to f (g is safe) and 1.0.2 up to beta1 (beta2 is safe).

It's listed at the top.

Here's a python script that can test a site for the vulnerability.

There's an online version here BUT that one logs the name and status of a tested site, as can be seen here so you might not want to use that...

One very big thing to note about this vulnerability:

For the 2-year period that this bug existed anybody who knew about the issue was capable of reading a vulnerable site's memory, including the location that housed your private key. That means if you acquired a certificate (self-generated or bought) and used it on a vulnerable server, you need to do the following:

1. Update your software to prevent further exploitation.

2. Revoke your certificate.

3. Generate a new private key.

4. Get a trusted third party to reissue you a signed cert.

That last one will cost you money but you originally paid good money to get a certificate so you could use an encrypted communication channel which would seem to indicate it's worth something to you to have this communication channel secure. The cornerstone of that encryption has been compromised and until you replace it you cannot trust the communication channel to be secure.

It wouldn't be a bad idea to change any and all server-local passwords either.

"Without using any privileged information or credentials we were able steal from ourselves the secret keys used for our X.509 certificates, user names and passwords, instant messages, emails and business critical documents and communication." Source

Note that this means your forum password should be considered suspect (i.e. public) now aswell. On all affected https websites which, I fear, includes this one.

There is also questions on the legality of the scanners. As scanning a site without the owners permissions is technically illegal. However as it's for good intentions, the law isn't being enforced.

Uh, no. Unless you have permission, written permission it best, it's illegal. PERIOD!
