NVD Description

Note: Versions mentioned in the description apply only to the upstream python313-Pillow package and not the python313-Pillow package as distributed by SLES. See How to fix? for SLES:16.0.0 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.
