  <title>PHP: Vulnerabilities in included PCRE and XML-RPC libraries</title>
  <synopsis>
    PHP makes use of an affected PCRE library and ships with an affected
    XML-RPC library and is therefore potentially vulnerable to remote execution
    of arbitrary code.

    <p>
    PHP is a general-purpose scripting language widely used to develop
    web-based applications. It can run inside a web server using the
    mod_php module or the CGI version of PHP, or can run stand-alone in a
    CLI.
    </p>

  <description>
    <p>
    PHP makes use of a private copy of libpcre which is subject to an
    integer overflow leading to a heap overflow (see GLSA 200508-17). It
    also ships with an XML-RPC library affected by a script injection
    vulnerability (see GLSA 200508-13).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could target a PHP-based web application that would
    use untrusted data as regular expressions, potentially resulting in the
    execution of arbitrary code. If web applications make use of the
    XML-RPC library shipped with PHP, they are also vulnerable to remote
    execution of arbitrary PHP code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PHP users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose dev-php/php</code>
    <p>
    All mod_php users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose dev-php/mod_php</code>
    <p>
    All php-cgi users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose dev-php/php-cgi</code>
  </resolution>
