A man-in-the-middle attacker could use this flaw to decryptand 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 beusing a vulnerable version of OpenSSL; the server must be using OpenSSLversion 1.0.1 and above, and the client must be using any version ofOpenSSL.
