Synopsis
========
Two buffer overflows in enscript might lead to the execution of
arbitrary code.
Background
==========
enscript is a powerful ASCII to PostScript file converter.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/enscript < 1.6.4-r4 >= 1.6.4-r4
Description
===========
Two stack-based buffer overflows in the read_special_escape() function
in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research
discovered a vulnerability related to the "setfilename" command
(CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability
related to the "font" escape sequence (CVE-2008-4306).
Impact
======
An attacker could entice a user or automated system to process
specially crafted input with the special escapes processing enabled
using the "-e" option, possibly resulting in the execution of arbitrary
code.
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-1.6.4-r4"
