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"
