description

Pillow through 12.3.0 can consume excessive memory when processing crafted TIFF files or images containing EXIF metadata. An attacker who can cause an application to open or inspect attacker-controlled images may exhaust the process memory, including when EXIF metadata is accessed.

mitigation

Upgrade Pillow to version 13.0.0 or later. Until upgraded, avoid processing untrusted TIFF or EXIF-bearing images and avoid requesting EXIF metadata from untrusted files.

fixed in 13.0.0
