"According to its banner, the version of Apache 2.2.x running on the
remote host is prior to 2.2.15. It is, therefore, potentially affected
by multiple vulnerabilities :

  - A TLS renegotiation prefix injection attack is possible. 
    (CVE-2009-3555)

  - The 'mod_proxy_ajp' module returns the wrong status code
    if it encounters an error which causes the back-end 
    server to be put into an error state. (CVE-2010-0408)

  - The 'mod_isapi' attempts to unload the 'ISAPI.dll' when
    it encounters various error states which could leave
    call-backs in an undefined state. (CVE-2010-0425)

  - A flaw in the core sub-request process code can lead to
    sensitive information from a request being handled by 
    the wrong thread if a multi-threaded environment is
    used. (CVE-2010-0434)

  - Added 'mod_reqtimeout' module to mitigate Slowloris
    attacks. (CVE-2007-6750)"
