All supported architectures
Warning: *: Needs to be manually updated
Multiple vulnerabilities were discovered in CSTeX, possibly allowing to
execute arbitrary code or overwrite arbitrary files.
CSTeX is a TeX distribution with Czech and Slovak support. It is used
for creating and manipulating LaTeX documents.
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).
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.
There is no known workaround at this time.
CSTeX is not maintained upstream, so the package was masked in Portage.
We recommend that users unmerge CSTeX:
Code Listing 3.1: Resolution
# emerge --unmerge app-text/cstetex
As an alternative, users should upgrade their systems to use teTeX or
TeX Live with its Babel packages.
