Notes:

- Reproduces on Adobe Acrobat Reader DC (2019.012.20036) on Windows 10, with and without PageHeap enabled.

- The crash occurs immediately after opening the PDF document, and is caused by attempting to write data outside of a heap-based buffer.

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

- We have minimized the difference between the original and mutated files down to 5 bytes inside of a binary JP2 image stream: 4 bytes at offset 0x195 changed from <FF FF E0 00> to <00 00 00 C0>, and 1 byte at offset 0x1ED changed from <0x53> to <0x5B>.
