Advisory ID: SLSA-2014:0680-1
Issue Date: 2014-06-10
CVE Numbers: CVE-2014-0224

It was found that OpenSSL clients and servers could be forced, via a
specially crafted handshake packet, to use weak keying material for
communication. A man-in-the-middle attacker could use this flaw to decrypt
and modify traffic between a client and a server. (CVE-2014-0224)

Note: In order to exploit this flaw, both the server and the client must
be using a vulnerable version of OpenSSL; the server must be using OpenSSL
version 1.0.1 and above, and the client must be using any version of
OpenSSL. For more information about this flaw, refer to:

For the update to take effect, all services linked to the OpenSSL library
(such as httpd and other SSL-enabled services) must be restarted or the
system rebooted.
