Summary

Pillow BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading

Details

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