GHSA-45HQ-CXWH-F6VC Pillow `BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading

Summary PIL/BdfFontFile.py bdfchar lines 84–88 reads the BBX width height field from a BDF font file and passes the dimensions directly to Image.new without calling Image.decompressionbombcheck. This completely bypasses Pillow's documented decompression bomb protection. Image.open enforces...

Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`

Description PIL/FontFile.py FontFile.compile assembles per-glyph images into a single combined bitmap using Image.new"1", xsize, ysize without calling Image.decompressionbombcheck. This is the base-class method shared by both BdfFontFile and PcfFontFile, and it is triggered whenever a loaded font...
