    Please reach out if anyone wants @trailofbits to apply better security engineering to ImageMagick, Ghostscript, etc. We're happy to dust off these codebases and bring them into 2018.https://twitter.com/lcamtuf/status/861027173401899009 …

    And if you're feeding user input to ImageMagick, ffmpeg, Ghostscript, etc w/o sandboxing, you're gonna get hurt. https://twitter.com/robertswiecki/status/860915149372362753 …

        Seriously, every giant technology company that inputs/outputs PDFs has uniquely "solved" dealing with Ghostscript. I would love it if one such firm contracted with us to fix it for everyone.

        I imagine submitting a series of patches to https://g.co/prp  would be a good way to round this up.

        It helps! But "patch rewards" and bug bounties in general are a passive reward mechanism that barely covers the cost of an active development effort.

        Would be interested to discuss this further (maybe offline? up to you). We made the PRP to make it financially worthy to make security improvements of the magnitude you are proposing. So if you have some feedback about this, would love to hear more.

        @FFmpeg is used everywhere. I suggest that the @vMixHD user community would love to see this done.
