  "title": "Out-of-bounds read in Pillow TIFF encoder",
  "summary": "Pillow versions before 13.0.0 can read beyond a ColorMap buffer while re-encoding a TIFF with retained metadata. An attacker who can supply a TIFF may cause a crash or possible process-memory disclosure when the application loads the image and saves it as TIFF using the affected encoder.",
  "mitigation": "Upgrade Pillow to version 13.0.0 or later. Until upgraded, avoid re-encoding untrusted TIFF files as TIFF and discard retained TIFF metadata before saving.",
