CVE-2026-65970: CWE-825: Expired Pointer Dereference in AcademySoftwareFoundation OpenImageIO
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.
AI Analysis
Technical Summary
OpenImageIO versions before 3.1.16.0 contain a use-after-scope vulnerability (CWE-825) in the TIFFInput::read_native_scanlines() function. When processing a specially crafted ZIP-compressed TIFF with TIFF multithreading enabled, the function may return through an error path while asynchronous strip-decompression tasks remain queued. Due to the order of variable declarations, objects captured by the task set are destroyed before the destructor waits for worker tasks to complete, allowing these tasks to access stale stack and heap memory. This results in a use-after-scope crash and denial of service. The vulnerability is fixed in version 3.1.16.0.
Potential Impact
The vulnerability can cause a denial of service via a crash when processing maliciously crafted TIFF images with multithreading enabled. There is no impact on confidentiality or integrity reported. The CVSS 3.1 base score is 5.3 (medium), reflecting network attack vector, high attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality or integrity impact, and high availability impact.
Mitigation Recommendations
A fix is available in OpenImageIO version 3.1.16.0. Users should upgrade to this version or later to remediate the vulnerability. No additional mitigation is indicated by the vendor advisory.
