[GLSA]

Gentoo Linux Security Advisory

Title: PTeX: Multiple vulnerabilities (GLSA 200805-13)
Severity: normal
Exploitable: remote
Date: May 12, 2008
Bug(s): #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: app-text/ptex
Vulnerable: < 3.1.10_p20071203
Unaffected: >= 3.1.10_p20071203
Architectures: 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:
