"It was discovered that texlive-base, the TeX Live package which
provides the essential TeX programs and files, whitelists mpost as an
external program to be run from within the TeX source code (called
\write18). Since mpost allows to specify other programs to be run, an
attacker can take advantage of this flaw for arbitrary code execution
when compiling a TeX document."
