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"
