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

-------------------------------------------------------------------

1 app-text/ptex < 3.1.10_p20071203 >= 3.1.10_p20071203

 

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"
