"According to its banner, the version of PHP installed on the remote
host is older than 5.2.10.  Such versions are reportedly affected by
multiple vulnerabilities :

  - Sufficient checks are not performed on fields reserved 
    for offsets in function 'exif_read_data()'. Successful 
    exploitation of this issue could result in a denial of 
    service condition. (bug 48378)

  - Provided 'safe_mode_exec_dir' is not set (not set by
    default), it may be possible to bypass 'safe_mode' 
    restrictions by preceding a backslash in functions 
    such as 'exec()', 'system()', 'shell_exec()', 
    'passthru()' and 'popen()' on a system running PHP 
    on Windows. (bug 45997)");
