When downloading media such as .mp4, .jpg, .png, and such, is it possible to sanitize it before viewing?
For example, it’s possible to exploit media players with malformed or crafted files from what I know. I’ve looked at possible solutions such as re encoding with FFmpeg but that comes with its own exploits when it parses the file for re encoding.
I’ve also read that removing exif data is another way, but doesn’t that come with the same issues as re encoding but with worse outputs in terms of sanitation?
If anyone knows of a tool that can be used without any permissions that might resolve these issues, let me know.
Or if there is a harderned viewer that can reduce potential exploits, that will be great too.
Thanks!
(I know that apps are sandboxed and the OS has built in memory corruption exploit prevention but would prefer extra protection)
