From 8.2.0 until 13.0.0, Pillow's tiled-TIFF decoder can read past the tile buffer while copying four-byte pixels. In _decodeTile, libtiff can return a tile allocation smaller than the required row stride multiplied by the tile length, and Pillow's stride-and-copy loop walks beyond that allocation. An attacker can supply a crafted tiled TIFF to an application that loads it. This can expose adjacent heap data in pixels or crash the process. This issue is fixed in version 13.0.0."}], "lastModified": "2026-10-28T16:17:01.987", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:python:pillow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BCBF8B77-A7E3-40B4-A29D-74D56B77101B", "versionEndExcluding": "13.0.0", "versionStartIncluding": "8.2.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
