If a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This has been fixed.
Update pillow to 12.2.0 if you use the affected versions. Test the change in a non-production environment first.
Local check
hol-guard supply-chain scanPillow has an integer overflow when processing fonts affects pillow (pip). Severity is medium. If a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This has been fixed.
AI coding agents often install or upgrade packages automatically in pip. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
