I recently ran into a requirement that needed a web server set up with SSL, to show that its possible to extract the private key from a server with a vulnerable version of OpenSSL (Heartbleed). Hence, I downloaded a version of Debian I knew that shipped with the vulnerable version of OpenSSL from here.

However after configuring it, it wasn't leaking anything (as reported by Metasploit).

Below is the output from openssl version -a:

OpenSSL 1.0.1e 11 Feb 2013
built on: Sat Jun 13 10:26:40 UTC 2015
platform: debian-amd64
options:  bn(64,64) rc4(16x,int) des(idx,cisc,16,int) blowfish(idx)
OPENSSLDIR: "/usr/lib/ssl"

From what I know, versions between 1.0.1 through to 1.0.1f are vulnerable. I can see that it was built on a later date. My questions are:

  1. Which compile option made it safe against Heartbleed? I don't see DOPENSSL_NO_HEARTBEATS flag option in the output above.

  2. Where can I get a Debian version (7 or later) which actually ships with the vulnerable version of OpenSSL needed to demo Heartbleed.

    They might have backported the patch.

As mentioned by @void_in, they backported the patch. Check your package version like so:

dpkg -l openssl

From 1.0.1e-2+deb7u5, the security patch has been included.:

openssl (1.0.1e-2+deb7u5) wheezy-security; urgency=high

  • Non-maintainer upload by the Security Team.
  • Add CVE-2014-0160.patch patch. CVE-2014-0160: Fix TLS/DTLS hearbeat information disclosure. 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.

The files relating to 1.0.1e-2+deb7u4 can be found here, and you should be able to revert back to a previous version of a package by adding entries in the /etc/apt/preferences file.

  • My OpenSSL version (using an LTS distro) is OpenSSL 1.0.1f 6 Jan 2014 - why do they keep the "2014", it's irritating. Shouldn't this date info be updated to the the day of the latest patch?
