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...

Pillow `PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading

Description PIL/PcfFontFile.py loadbitmaps line 227 reads glyph dimensions from the PCF METRICS section and passes them directly to Image.frombytes without calling Image.decompressionbombcheck. Dimensions originate from unsigned 16-bit values: xsize = right - left max: 65535 − 0 = 65535 ysize =...
