  "title": "Out-of-bounds read in Pillow TIFF decoding",
  "summary": "Pillow versions before 13.0.0 can read beyond a decode buffer when processing malformed TIFF images with inconsistent image metadata. An attacker who can cause an application to open and load such an image may expose process-memory bytes in decoded output or crash the image-processing process.",
