CyberRota Analysis
AI-GeneratedOpenImageIO versions prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1 are vulnerable to a heap out-of-bounds write due to improper handling of crafted cineon images with unsupported component bit depth 26, leading to potential memory corruption. This vulnerability can allow attackers to manipulate memory, potentially resulting in arbitrary code execution or application crashes. Organizations using OpenImageIO for image processing, especially in VFX or animation, should prioritize upgrading to the patched versions to mitigate this risk.

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 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted cineon image can declare unsupported component bit depth 26. cineoninput::open() maps it to a 32-bit imagespec, but libcineon maps the unsupported depth to an 8-byte value, so cineoninput::read_native_scanline() causes attacker-controlled data to be written beyond the 4-byte-per-pixel caller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), CineonInput::read_native_scanline(), ComponentDataSize(), bit depth 26, and ImageSpec, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.
