CVE-2026-43908 Details
Description
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the pixel-loop index expression i * 3 inside ConvertCbYCrYToRGB() causes the function to compute a large negative pointer offset into the output buffer, producing an out-of-bounds write that crashes the process. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
A signed 32-bit integer overflow vulnerability has been identified in OpenImageIO, a toolset for image file manipulation relevant to VFX and animation. This issue exists in versions prior to 3.0.18.0 and 3.1.13.0. The vulnerability arises in the DPX 4:2:2 decoder within the ConvertCbYCrYToRGB() function. The pixel-loop index expression 'i * 3' can overflow, causing a large negative pointer offset that leads to an out-of-bounds write, crashing the process. The vulnerability can be exploited by processing a crafted DPX file that exceeds a certain pixel count, triggering the overflow and subsequent crash.
Users can upgrade to OpenImageIO versions 3.0.18.0 or 3.1.13.0, where this vulnerability has been fixed.
