Crash when loading JP2 image depending on openjpeg version #8784

What did you do?

Trying to load and get data from a jp2 image
000137.zip

When working on my dataset, this issue occurred for ~50% of the images, but not for the remainder, so is intermittent.

This worked for me on a previously created python environment, but not a fresh one I created today (with nothing but conda install pillow). After some debugging on my end, I was able to determine that the error does NOT occur when downgrading to openjpeg version 2.4.0, but does occur with openjpeg version 2.5.2. The only difference in the PIL.report is the openjpeg version, and I'm able to repeatably break/fix the issue by upgrading/downgrading openjpeg.

I don't know if that makes in an openjpeg problem or a pillow problem, but I'm reporting here because this is the only imaging library I am familiar with, and thus the only place I know how to test and produce the error.

What did you expect to happen?

File loads and yields data

What actually happened?

Code crashes with the following error

  File "<python-input-1>", line 1, in <module>
    _ = Image.open('000137.jp2').getdata()
  File "D:\Code\Miniconda\envs\piltest\Lib\site-packages\PIL\Image.py", line 1456, in getdata
