 2014-04-07: 21:00:: we got aware of a OpenSSL vulnerability in OpenSSL's support for the TLS/DTLS Heartbeat extension. Memory from either client or server can be recovered by an attacker. This vulnerability might allow an attacker to compromise the private key and other sensitive data in memory.
 2014-04-08: 06:30:: Relying on the updates of our used distribution we rolled out the update and had at this time already patched versions on all vulnerable servers.
 2014-04-10: 08:00:: Updates were rolled out also on Clients side.
 2014-04-14: 12:00:: OpenSSL certificates are replaced for previously affected services on the vulnerable servers.
 2014-04-16: 16:00:: Informatikdienste announce that they also patched all relevant services and advice customers to change the password. We confirm that this step is '''strongly recommended'''. Note in particular that the vulnerability was already exploited since November 2013 to collect passwords, session data, private keys, etc.
