{"cve":"CVE-2026-59189","nvd":{"published":"2026-08-25T17:17:37.160","modified":"2026-09-09T21:07:31.353","status":"Deferred","description":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In OpenEXRUtil versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.12, the documented TypedDeepImageChannel<T>::row() API can return an out-of-bounds pointer when a deep image has a non-zero dataWindow origin, resulting in a heap out-of-bounds read and crash, with potential information disclosure under a controlled heap layout. The flaw arises because ImfDeepImageChannel uses two conflicting coordinate models: at(x, y) uses absolute coordinates (with _base offset by dataWindow.min), while row(r) is documented as 0-based logical access. For a non-zero dataWindow.min, row(0) therefore points outside the _sampleListPointers allocation instead of at the first logical row. This issue is fixed in versions 3.3.13 and 3.4.13.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://github.com/AcademySoftwareFoundation/openexr/commit/37f03b6ed90f3dd9910f31de3a40f25f2bc2aca1","https://github.com/AcademySoftwareFoundation/openexr/commit/55b7958ecb5ac32c427ff39c1e063f6f7bbee77c","https://github.com/AcademySoftwareFoundation/openexr/commit/aef02224ba282a802de65d16c49c1cdb82089dec","https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-hwmv-39v6-739m","https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-hwmv-39v6-739m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-59189","score":0.0031,"percentile":0.23889,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
