Synopsis
========

enscript suffers from vulnerabilities and design flaws, potentially
resulting in the execution of arbitrary code.

Background
==========

enscript is a powerful ASCII to PostScript file converter.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  app-text/enscript     < 1.6.3-r3                      >= 1.6.3-r3

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

Erik Sjolund discovered several issues in enscript: it suffers from
several buffer overflows (CAN-2004-1186), quotes and shell escape
characters are insufficiently sanitized in filenames (CAN-2004-1185),
and it supported taking input from an arbitrary command pipe, with
unwanted side effects (CAN-2004-1184).

Impact
======

An attacker could design malicious files or input data which, once
feeded into enscript, would trigger the execution of arbitrary code
with the rights of the user running enscript.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All enscript users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.3-r3"
