For those of you who haven't heard, DROWN is a vulnerability in SSL. In short, there are already plenty of complicated descriptions out there but in short if you server supports SSLv2 (that is on any service like POP3 or IMAP not just HTTPS) an attacker could easily crack the private key from that certificate and therefor has also the private key to every other service that uses that certificate.
