    <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 and also stand-alone in a CLI.
    </p>

  <description>
    <p>
    Multiple vulnerabilities have been found and fixed in PHP:
    </p>
    <ul>
    <li>a possible $GLOBALS variable overwrite problem through file
    upload handling, extract() and import_request_variables()
    (CVE-2005-3390)</li>
    <li>a local Denial of Service through the use of
    the session.save_path option (CVE-2005-3319)</li>
    <li>an issue with
    trailing slashes in allowed basedirs (CVE-2005-3054)</li>
    <li>an issue
    with calling virtual() on Apache 2, allowing to bypass safe_mode and
    open_basedir restrictions (CVE-2005-3392)</li>
    <li>a problem when a
    request was terminated due to memory_limit constraints during certain
    parse_str() calls (CVE-2005-3389)</li>
    <li>The curl and gd modules
    allowed to bypass the safe mode open_basedir restrictions
    (CVE-2005-3391)</li>
    <li>a cross-site scripting (XSS) vulnerability in
    phpinfo() (CVE-2005-3388)</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    Attackers could leverage these issues to exploit applications that
    are assumed to be secure through the use of proper register_globals,
    safe_mode or open_basedir parameters. Remote attackers could also
    conduct cross-site scripting attacks if a page calling phpinfo() was
    available. Finally, a local attacker could cause a local Denial of
    Service using malicious session.save_path options.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround that would solve all issues 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>
