    Synopsis
    ========

    Zope is vulnerable to a file inclusion vulnerability when exposing
    RestructuredText functionalities to untrusted users.

    Background
    ==========

    Zope is an application server that can be used to build content
    management systems, intranets, portals or other custom applications.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-zope/zope < 2.7.8 >= 2.7.8
         net-zope/zope == 2.8.0
         net-zope/zope == 2.8.1

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

    Zope honors file inclusion directives in RestructuredText objects by
    default.

    Impact
    ======

    An attacker could exploit the vulnerability by sending malicious input
    that would be interpreted in a RestructuredText Zope object,
    potentially resulting in the execution of arbitrary Zope code with the
    rights of the Zope server.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Zope users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose net-zope/zope

    References
