"According to its banner, the version of PHP 5.3.x installed on the
remote host is prior to 5.3.22.  It is, therefore, potentially 
affected by the following vulnerabilities :

  - An error exists in the file 'ext/soap/soap.c'
    related to the 'soap.wsdl_cache_dir' configuration
    directive and writing cache files that could allow
    remote 'wsdl' files to be written to arbitrary
    locations. (CVE-2013-1635)

  - An error exists in the file 'ext/soap/php_xml.c'
    related to parsing SOAP 'wsdl' files and external
    entities that could cause PHP to parse remote XML
    documents defined by an attacker. This could allow
    access to arbitrary files. (CVE-2013-1643)

Note that this plugin does not attempt to exploit the vulnerabilities
but, instead relies only on PHP's self-reported version number.");
