If your site is protected by CloudFlare (like HN is), you are automatically protected from this vulnerability (see: http://blog.cloudflare.com/staying-ahead-of-openssl-vulnerab... ).

You are protected now. But you were not before, so if any attacker figured this out before the public disclosure then you have [possibly] already been attacked and compromised.

An Ubuntu update would be nice right about now. Outside of disabling everything that uses openssl or compiling a new one manually, there's not much I can do to secure my servers at this moment. Meanwhile, I'm guessing a lot of not so nice people are racing to scan IP ranges for this bug.

FreeBSD updated (run the update about 40 minutes ago).

Earlier quoted context omitted.

Totally agreed on the over-complexity and un-securability of TLS, that too often is deployed where something simpler should be used instead. However, wouldn't OpenSSH be the thing spiped replaces most of the times? And that has a better security track record (I mean, better than OpenSSL for sure).

A lot of people are doing spiped-like things using stunnel.

Basically, for internal infrastructure, where autossh wont work and/or where something simpler than ssh is desired.

So the strawmen arguments about it not replacing TLS is not the point.

stud, nginx, stunnel, f5 load balancers and cloudflare will still be needed for now, until 'moxie0 or someone comes up with a viable CA alternative AND something way, way simpler than TLS (brain-hurt ASN1, even with Wireshark).

Are Android or iOS affected? Android seems to ship openssl 1.0.

Could a malicious server attack clients? Perhaps expose a browser's cookie jar or other saved passwords in memory?

The number of installed openssl clients across all devices and computers must be quite large.

In case anyone was wondering why I wrote spiped...

But isn't spiped mostly irrelevant here? I mean, it's not a TLS replacement, as it's based on PSK (thus only useable between two mutually trusting peers like me and myself), not PKI.

spiped should be irrelevant here. But there are a lot of people using PKI where they could be using PSK.

Can we please vote this link higher? It's got a ton of information in it.

It's already at the top of the homepage, as a separate submission.

It is now. It wasn't at the time of vacri's post. Top of the homepage is best.

If you'd like to update the keg-only OpenSSL brew on osx, and dont care for legacy and crap:

     ( export CONFIGURE_OPTS='no-hw no-rdrand \
       no-sctp no-md4 no-mdc2 no-rc4 no-fips no-engine'; \
  brew install https://gist.github.com/steakknife/8228264/raw/openssl.rb )
Beware, that by default on osx/ios, pretty much everything links to sketchy CommonCrypto or a crusty, quasi-deprecated 0.9.8.

Yes, the vulnerable code is used by both client and server so any client using openssl is affected.

OpenSSL doesn't seem to be installed on my jailbroken iPhone.
