    Synopsis
    ========

    A vulnerability in phpBB allows a remote attacker to execute arbitrary
    commands with the rights of the web server.

    Background
    ==========

    phpBB is an Open Source bulletin board package.

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

    Ron van Daal discovered that phpBB contains a vulnerability in the
    highlighting code.

    Impact
    ======

    Successful exploitation would grant an attacker unrestricted access to
    the PHP exec() or system() functions, allowing the execution of
    arbitrary commands with the rights of the web server.

    Workaround
    ==========

    Please follow the instructions given in the phpBB announcement.

    Resolution
    ==========

    The phpBB package is no longer supported by Gentoo Linux and has been
    removed from the Portage repository, no further announcements will be
    issued regarding phpBB updates. Users who wish to continue using phpBB
    are advised to monitor and refer to www.phpbb.com for more information.

    To continue using the Gentoo-provided phpBB package, please refer to
