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:
# emerge --unmerge app-text/cstetex
As an alternative, users should upgrade their systems to use teTeX or TeX Live with its Babel packages.
