(CSTeX: Multiple vulnerabilities)

    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.");

    We recommend that users unmerge CSTeX:

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