    Synopsis
    ========

    PhpWiki includes PHP XML-RPC code which is vulnerable to arbitrary
    command execution.

    Background
    ==========

    PhpWiki is an application that creates a web site where anyone can edit
    the pages through HTML forms.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 www-apps/phpwiki < 1.3.10-r2 >= 1.3.10-r2

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

    Earlier versions of PhpWiki contain an XML-RPC library that improperly
    handles XML-RPC requests and responses with malformed nested tags.

    Impact
    ======

    A remote attacker could exploit this vulnerability to inject arbitrary
    PHP script code into eval() statements by sending a specially crafted
    XML document to PhpWiki.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All PhpWiki users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=www-apps/phpwiki-1.3.10-r2"
