"The version of Adobe Flash Media Server running on the remote host is
earlier than version 3.5.6 or 4.0.2.  Such versions are potentially
affected by the following vulnerabilities :

  - The server is affected by a memory corruption issue due 
    to a race condition in the TLS extension code provided
    by the bundled version of OpenSSL. A remote attacker 
    may be able to exploit this vulnerability to execute 
    arbitrary code on the server. (CVE-2010-3864)

    due to an unspecified error related to processing 
    certain XML content. (CVE-2011-0612)");
