"According to its banner, the version of PHP installed on the remote
host is older than 5.3.9.  As such, it may be affected by the following
security issues :

  - The 'is_a()' function in PHP 5.3.7 and 5.3.8 triggers a 
    call to '__autoload()'. (CVE-2011-3379)

  - It is possible to create a denial of service condition 
    by sending multiple, specially crafted requests 
    containing parameter values that cause hash collisions 
    when computing the hash values for storage in a hash 
    table.  (CVE-2011-4885)
   
  - An integer overflow exists in the exif_process_IFD_TAG 
    function in exif.c that can allow a remote attacker to 
    read arbitrary memory locations or cause a denial of 
    service condition.  This vulnerability only affects PHP 
    5.4.0beta2 on 32-bit platforms. (CVE-2011-4566)

  - Calls to libxslt are not restricted via
    xsltSetSecurityPrefs(), which could allow an attacker
    to create or overwrite files, resulting in arbitrary
    code execution. (CVE-2012-0057)

  - An error exists in the function 'tidy_diagnose' that
    can allow an attacker to cause the application to 
    dereference a NULL pointer. This causes the application
    to crash. (CVE-2012-0781)

  - The 'PDORow' implementation contains an error that can
    cause application crashes when interacting with the 
    session feature. (CVE-2012-0788)

  - An error exists in the timezone handling such that
    repeated calls to the function 'strtotime' can allow
    a denial of service attack via memory consumption.
    (CVE-2012-0789)");
