Description Pedro Sampaio 2017-12-14 21:10:26 UTC

TeX Live through 20170524 does not validate strings before launching the
   program specified by the BROWSER environment variable, which might allow
   remote attackers to conduct argument-injection attacks via a crafted URL,
   related to texmf-dist/scripts/context/stubs/mswin/mtxrun.lua and
   texmf-dist/tex/luatex/lualibs/lualibs-os.lua.
