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 linked_scripts/context/stubs/unix/mtxrun, texmf-dist/scripts/context/stubs/mswin/mtxrun.lua, and texmf-dist/tex/luatex/lualibs/lualibs-os.lua.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
