NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-pillow package and not the py3-pillow package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's P;2L and P;4L raw decoders can read past the end of an input buffer. ImagingRawDecode calculates a packed-pixel row size, while the unpackers read separately padded bit planes. A caller can supply a buffer and image dimensions whose accepted size is smaller than the unpacker's actual footprint. This can disclose up to three adjacent heap bytes in output pixels or crash the process. This issue is fixed in version 13.0.0.
