Note: Versions mentioned in the description apply only to the upstream open-webui package and not the open-webui package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
