{"id":"CVE-2026-65970","published":"2026-09-18T16:17:08.590","lastModified":"2026-09-24T21:22:19.873","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.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-825"],"vendors":[],"products":[],"references":[{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/31201c22df477b105b105c0dcfbf5d3d46db431b","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5294","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.16.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836","tags":[]}],"exploitRefs":[{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/31201c22df477b105b105c0dcfbf5d3d46db431b","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5294","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.16.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-v278-gpwr-r836","tags":[]}],"hasPoc":true,"ai":null}
