{"schemaVersion":3,"id":"CVE-2026-65970","aliases":["UBUNTU-CVE-2026-65970"],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-09-18T15:41:36.413Z","modified":"2026-09-18T16:43:54.088Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
