    Synopsis
    ========

    MediaWiki is vulnerable to a cross-site scripting attack that could
    allow arbitrary JavaScript code execution.

    Background
    ==========

    MediaWiki is a collaborative editing software, used by big projects
    like Wikipedia.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 www-apps/mediawiki < 1.4.7 >= 1.4.7

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

    MediaWiki fails to escape a parameter in the page move template
    correctly.

    Impact
    ======

    By enticing a user to visit a specially crafted URL, a remote attacker
    could exploit this vulnerability to inject malicious JavaScript code
    that will be executed in a user's browser session in the context of the
    vulnerable site.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All MediaWiki users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=www-apps/mediawiki-1.4.7"
