Background ========== CSTeX is a TeX distribution with Czech and Slovak support. It is used for creating and manipulating LaTeX documents. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/cstetex < 2.0.2-r2 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. ------------------------------------------------------------------- ------------------------------------------------------------------- NOTE: Packages marked with asterisks require manual intervention! 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: # emerge --unmerge app-text/cstetex As an alternative, users should upgrade their systems to use teTeX or TeX Live with its Babel packages.
