Notes:

- Reproduces on Adobe Acrobat Reader DC (2019.012.20035) on Windows 10, with the PageHeap option enabled in Application Verifier.

- The crash occurs immediately after opening the PDF document.

- Attached samples: poc.pdf (crashing file), original.pdf (original file).

- We have minimized the difference between the original and mutated files down to a single byte at offset 0x172b4, which appears to reside inside a binary JP2 image stream. It was modified from 0x1C to 0xFF.
