    Synopsis
    ========

    PHP suffers from multiple issues, resulting in security functions
    bypass, local Denial of service, cross-site scripting or PHP variables
    overwrite.

    Background
    ==========

    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.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-php/php < 4.4.0-r4 *>= 4.3.11-r4
    >= 4.4.0-r4
      2 dev-php/mod_php < 4.4.0-r8 *>= 4.3.11-r4
    >= 4.4.0-r8
      3 dev-php/php-cgi < 4.4.0-r5 *>= 4.3.11-r5
    >= 4.4.0-r5
        -------------------------------------------------------------------
         3 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

    Description
    ===========

    Multiple vulnerabilities have been found and fixed in PHP:

    * a possible $GLOBALS variable overwrite problem through file upload
      handling, extract() and import_request_variables() (CVE-2005-3390)

    * a local Denial of Service through the use of the session.save_path
      option (CVE-2005-3319)

    * an issue with trailing slashes in allowed basedirs (CVE-2005-3054)

    * an issue with calling virtual() on Apache 2, allowing to bypass
      safe_mode and open_basedir restrictions (CVE-2005-3392)

    * a problem when a request was terminated due to memory_limit
      constraints during certain parse_str() calls (CVE-2005-3389)

    * The curl and gd modules allowed to bypass the safe mode
      open_basedir restrictions (CVE-2005-3391)

    * a cross-site scripting (XSS) vulnerability in phpinfo()
      (CVE-2005-3388)

    Impact
    ======

    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.

    Workaround
    ==========

    There is no known workaround that would solve all issues at this time.

    Resolution
    ==========

    All PHP users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose dev-php/php

    All mod_php users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose dev-php/mod_php

    All php-cgi users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose dev-php/php-cgi
