"According to its banner, the version of PHP installed on the remote
host is older than 5.2.12.  Such versions may be affected by several
security issues :

  - It is possible to bypass the 'safe_mode' configuration
    setting using 'tempnam()'. (CVE-2009-3557)

  - It is possible to bypass the 'open_basedir' 
    configuration setting using 'posix_mkfifo()'. 
    (CVE-2009-3558)

  - Provided file uploading is enabled (it is by default),
    an attacker can upload files using a POST request with
    'multipart/form-data' content even if the target script
    doesn't actually support file uploads per se.  By 
    supplying a large number (15,000+) of files, an attacker
    could cause the web server to stop responding while it
    processes the file list. (CVE-2009-4017)

  - Missing protection for '$_SESSION' from interrupt
    corruption and improved 'session.save_path' check.
    (CVE-2009-4143)

  - Insufficient input string validation in the 
    'htmlspecialchars()' function. (CVE-2009-4142)");
