GLSA 200502-03: enscript: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	normal
Title:	enscript: Multiple vulnerabilities
Date:	02/02/2005
Bugs:	#77408
ID:	200502-03

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	Architecture(s)
app-text/enscript	< 1.6.3-r3	>= 1.6.3-r3	All supported architectures

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"
