GLSA 200805-13: PTeX: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	normal
Title:	PTeX: Multiple vulnerabilities
Date:	05/12/2008
Bugs:	#196673
ID:	200805-13

Synopsis

Multiple vulnerabilities were discovered in PTeX, possibly allowing the execution of arbitrary code or overwriting arbitrary files.

Background

PTeX is a TeX distribution with Japanese support. It is used for creating and manipulating LaTeX documents.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/ptex	< 3.1.10_p20071203	>= 3.1.10_p20071203	All supported architectures

Description

Multiple issues were found in the teTeX 2 codebase that PTeX builds upon (GLSA 200709-17, GLSA 200711-26). PTeX also includes vulnerable code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12, GLSA 200711-22) and from T1Lib (GLSA 200710-12).

Impact

Remote attackers could possibly execute arbitrary code and local attackers could possibly overwrite arbitrary files with the privileges of the user running PTeX via multiple vectors, e.g. enticing users to open specially crafted files.

Workaround

There is no known workaround at this time.

Resolution

All PTeX users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/ptex-3.1.10_p20071203"
