Gentoo Linux Security Advisory

Title: CSTeX: Multiple vulnerabilities (GLSA 200711-34)
Severity: normal
Exploitable: remote
Date: November 25, 2007
Bug(s): #196673
ID: 200711-34

Synopsis


Multiple vulnerabilities were discovered in CSTeX, possibly allowing to
execute arbitrary code or overwrite arbitrary files.


Background


CSTeX is a TeX distribution with Czech and Slovak support. It is used
for creating and manipulating LaTeX documents.


Affected Packages

Package: app-text/cstetex
Vulnerable: < 2.0.2-r2
Architectures: All supported architectures


Description


Multiple issues were found in the teTeX 2 codebase that CSTeX builds
upon (GLSA 200709-17, GLSA 200711-26). CSTeX 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 CSTeX via multiple vectors.


Workaround


There is no known workaround at this time.


Resolution


CSTeX is not maintained upstream, so the package was masked in Portage.
We recommend that users unmerge CSTeX:
Code:
# emerge --unmerge app-text/cstetex

As an alternative, users should upgrade their systems to use teTeX or
TeX Live with its Babel packages.
