Tim Allison commented on TIKA-3642:
-----------------------------------
The key point [~tilman] makes is that "tika will fail", not just on PDFs but on
many files. Running untrusted code on untrusted input is inherently dangerous;
this isn't just an issue with Tika. Take a look at recent iOS updates or
security notices from Adobe or Microsoft and you're likely to find critical
security fixes to parsers. See:
