"According to its banner, the version of PHP installed on the remote
host is earlier than 5.2.8.  As such, it is potentially affected by
the following vulnerabilities :

  - PHP fails to properly sanitize error messages of
    arbitrary HTML or script code, would code allow for 
    cross-site scripting attacks if PHP's 'display_errors' 
    setting is enabled. (CVE-2008-5814)

  - Version 5.2.7 introduced a regression with regard to
    'magic_quotes' functionality due to an incorrect fix to 
    the filter extension.  As a result, the 
    'magic_quotes_gpc' setting remains off even if it is set 
    to on. (CVE-2008-5844)");
