NVD Description

Note: Versions mentioned in the description apply only to the upstream mlflow package and not the mlflow package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdf_char() read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new() without calling Image._decompression_bomb_check(), bypassing Pillow's documented decompression bomb protection and allowing excessive memory allocation. This issue is fixed in version 12.3.0.
