How to fix?

Upgrade Pillow to version 9.1.1 or higher.


Pillow is a PIL (Python Imaging Library) fork.

Affected versions of this package are vulnerable to Heap-based Buffer Overflow. When reading a TGA file with RLE packets that cross scan lines. Pillow reads the information past the end of the first line without deducting that from the length of the remaining file data.
