------------------------------------------------------------------------
Pardus Linux Security Advisory 2008-41            security@...dus.org.tr
------------------------------------------------------------------------
       Date: 2008-09-06
   Severity: 2
       Type: Remote
------------------------------------------------------------------------

Summary
=======

Romain Francoise has found a security risk in a feature  of  GNU  Emacs
related to how Emacs interacts with Python.

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

The vulnerability may allow an attacker to run malicious  code  if  the
user runs the Emacs command `run-python' while the current directory is
world-writable, or if the user toggles `eldoc-mode' and visits a Python
source file in a world-writable directory.

Affected packages:

   Pardus 2008:
     emacs, all before 23.0.60_20080624-22-6
   Pardus 2007:
     emacs, all before 22.1-17-17

Resolution
==========

There are update(s) for emacs. You can update them via Package  Manager
or with a single command from console:

   Pardus 2008:
     pisi up emacs

   Pardus 2007:
     pisi up emacs
