Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-glyph images into a combined bitmap with Image.new("1", (xsize, ysize)) without calling Image. decompression bomb check(), allowing a font to trigger excessive allocation during conversion or saving. This issue is fixed in version 12.3.0.
