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."}], "lastModified": "2026-09-29T18:55:22.617", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openimageio:openimageio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "826C78E2-41E8-4051-9C61-F81D15230FAE", "versionEndExcluding": "3.1.16.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
