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
