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.","state":0,"publishedAt":"2026-10-19T20:59:15.098+00:00","modifiedAt":"2026-10-19T20:59:15.098+00:00","affected":[{"ecosystem":"Vendor product","name":"Pillow","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"python-pillow\",\n                    \"product\": \"Pillow\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 8.2.0, < 13.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/python-pillow/Pillow/security/advisories/GHSA-462x-pgg6-55fp","https://github.com/python-pillow/Pillow/commit/76869efdbbf2ad7dccd7536520fb61b7a00ab61e","https://github.com/python-pillow/Pillow/releases/tag/13.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112395","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112395","identifiers":["CVE-2026-112395"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
