Versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 allow a crafted EXR with a nonzero dataWindow.min to make TypedFlatImageChannel::row() return an invalid heap pointer, causing out-of-bounds or use-after-free writes. This occurs when an application writes rows through FlatHalfChannel::row(). Affected consumers are tools, converters, render pipeline components, or image-processing services that accept untrusted EXR files and use FlatHalfChannel::row() on loaded images. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.","published":"2026-08-25T17:17:36.603","modified":"2026-08-25T17:17:36.603","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/AcademySoftwareFoundation/openexr/commit/37f03b6ed90f3dd9910f31de3a40f25f2bc2aca1","label":"AcademySoftwareFoundation/openexr@37f03b6"},"references":[{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/37f03b6ed90f3dd9910f31de3a40f25f2bc2aca1"},{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/55b7958ecb5ac32c427ff39c1e063f6f7bbee77c"},{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/aef02224ba282a802de65d16c49c1cdb82089dec"},{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-pqp9-558c-453q"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-25T17:17:36.603"}}
