{"id":"BIT-pillow-2026-112395","summary":"Pillow tiled-TIFF decoder reads past tile buffer in copy4 (Unpack.c:1290)","details":"Pillow is a Python imaging library. 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.","aliases":["CVE-2026-112395","GHSA-462x-pgg6-55fp"],"modified":"2026-10-27T09:30:02.462926978Z","published":"2026-10-26T05:55:37.036Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:python:pillow:*:*:*:*:*:python:*:*"]},"references":[{"type":"FIX","url":"https://github.com/python-pillow/Pillow/commit/76869efdbbf2ad7dccd7536520fb61b7a00ab61e"},{"type":"ARTICLE","url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0"},{"type":"ADVISORY","url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-462x-pgg6-55fp"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112395"}],"affected":[{"package":{"name":"pillow","ecosystem":"Bitnami","purl":"pkg:bitnami/pillow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.2.0"},{"fixed":"13.0.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/pillow/BIT-pillow-2026-112395.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"}]}],"schema_version":"1.9.2"}
