I added a transcript, if I messed up on anything, I'm sorry! 173.245.55.73 06:08, 9 April 2014 (UTC)

Thanks for the transcript! (nothing seems messed up) 141.101.88.206 06:41, 9 April 2014 (UTC)
But wait! You forgot a comma! (It's okay, I fixed it :) ) 108.162.216.67 06:47, 9 April 2014 (UTC)

Is Explainxkcd using Open SSL? Jonv4n (talk) 06:56, 9 April 2014 (UTC)

I'd just like to take this moment to say that even though you probably don't have anything of value stored here, Explain xkcd is good on the Heartbleed front. Not using any of the affected software because the data we handle isn't private at all probably helps with that. And yes, Mediawiki hashes your passwords before they're sent.

Have the following from OpenSSL Bug Report Should this be incorperated into the main explanation, and how should it be formated Jonv4n (talk) 08:07, 9 April 2014 (UTC)



OpenSSL Security Advisory [07 Apr 2014]

============================

TLS heartbeat read overrun (CVE-2014-0160)

==============================

A missing bounds check in the handling of the TLS heartbeat extension can be used to reveal up to 64k of memory to a connected client or server.

Only 1.0.1 and 1.0.2-beta releases of OpenSSL are affected including 1.0.1f and 1.0.2-beta1.

Thanks for Neel Mehta of Google Security for discovering this bug and to Adam Langley <[email protected]> and Bodo Moeller <[email protected]> for preparing the fix.

Affected users should upgrade to OpenSSL 1.0.1g. Users unable to immediately upgrade can alternatively recompile OpenSSL with -DOPENSSL_NO_HEARTBEATS.

1.0.2 will be fixed in 1.0.2-beta2.


Actually, attack is limited to data in memory of the webserver PROCESS. Even on affected computers, other applications are safe and most of disk content is safe. Not speaking about the fact that in many cases, the public-facing webserver is just proxy cache before the real ones. The real problem is if someone immediately used the revealed data - either to impersonate the server or for example found the admin password and used it to copy the database ... which DOES leave traces. I agree with Cueball: there can be worse kind of bug. In fact, I'm sure that what Edward Snowden revealed is worse, although not technically bug. -- Hkmaly (talk) 10:18, 9 April 2014 (UTC)
Hkmaly -- Completely agree. Posted a similar discussion at security.stackexchange.com and altered the text here to describe heartbleed in more detail. Jimbob (talk) 21:33, 9 April 2014 (UTC)
