CyberRota Analysis
AI-GeneratedOpenImageIO versions prior to 3.1.16.0 are vulnerable to a use-after-scope condition caused by improper handling of multithreaded TIFF decompression, which can lead to crashes and denial of service. This issue arises when a crafted ZIP-compressed TIFF file is processed, allowing worker tasks to access stale memory. Organizations utilizing OpenImageIO for image file manipulation, particularly in VFX or animation, should prioritize upgrading to the patched version to mitigate potential disruptions.

Original NVD 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.
