    Synopsis
    ========

    Smarty's "Template security" feature can be bypassed, potentially
    allowing a remote attacker to execute arbitrary PHP code.

    Background
    ==========

    Smarty is a template engine for PHP. The "template security" feature of
    Smarty is designed to help reduce the risk of a system compromise when
    you have untrusted parties editing templates.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-php/smarty < 2.6.8 >= 2.6.8

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

    A vulnerability has been discovered within the regex_replace modifier
    of the Smarty templates when allowing access to untrusted users.

    Impact
    ======

    This issue may allow a remote attacker to bypass the "template
    security" feature of Smarty, and execute arbitrary PHP code.

    Workaround
    ==========

    Do not grant template access to untrusted users.

    Resolution
    ==========

    All Smarty users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-php/smarty-2.6.8"
