NVD Description

Note: Versions mentioned in the description apply only to the upstream python311-Pillow package and not the python311-Pillow package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile._open() read image dimensions from the GD 2.x header and stored them in self._size without calling Image._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0.
