"According to its banner, the version of Apache 2.2.x running on the 
remote host is prior to 2.2.14. It is, therefore, potentially affected
by multiple vulnerabilities :

  - Faulty error handling in the Solaris pollset support 
    could lead to a denial of service. (CVE-2009-2699)

  - The 'mod_proxy_ftp' module allows remote attackers to 
    bypass intended access restrictions. (CVE-2009-3095)

  - The 'ap_proxy_ftp_handler' function in 
    'modules/proxy/proxy_ftp.c' in the 'mod_proxy_ftp' 
    module allows remote FTP servers to cause a 
    denial of service. (CVE-2009-3094)

Note that the remote web server may not actually be affected by these
vulnerabilities as Nessus did not try to determine whether the affected
modules are in use or check for the issues themselves."  );
