NVD Description

Note: Versions mentioned in the description apply only to the upstream python-pillow-doc package and not the python-pillow-doc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Pillow is a Python imaging library. From version 11.2.1 to before version 12.2.0, passing nested lists as coordinates to APIs that accept coordinates such as ImagePath.Path, ImageDraw.ImageDraw.polygon and ImageDraw.ImageDraw.line could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists are now validated to contain exactly two numeric coordinates. This issue has been patched in version 12.2.0.
