{"cve":"CVE-2026-65970","nvd":{"published":"2026-09-18T16:17:08.590","modified":"2026-09-29T18:55:22.617","status":"Analyzed","description":"OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.1.16.0, a crafted ZIP-compressed TIFF processed with TIFF multithreading enabled can make TIFFInput::read_native_scanlines() return through an error path while asynchronous strip-decompression work remains queued. Because task_set is declared before ok and compressed_scratch, those captured objects are destroyed before the task-set destructor waits, allowing worker tasks to use stale stack and heap storage, resulting in a use-after-scope crash and denial of service. The affected implementation is identified by src/tiff.imageio/tiffinput.cpp, TIFFInput::read_native_scanlines(), task_set, ok, compressed_scratch, and uncompress_one_strip(), which define the relevant source path, functions, state, and trigger. This issue is fixed in 3.1.16.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.3},"cwes":["CWE-825"],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/31201c22df477b105b105c0dcfbf5d3d46db431b","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5294","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.16.0","https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836","https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836"],"products":["openimageio:openimageio"],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-65970","score":0.00424,"percentile":0.36716,"date":"2026-11-01"},"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).
