CVE-2026-43907 OpenImageIO: Integer overflow in QueryRGBBufferSizeInternal leads to heap out-of-bounds write in DPX decoder (kCbYCr and kABGR)

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 integer overflow in QueryRGBBufferSizeInternal in DPXColorConverter.cpp leads to a heap-based out-of-bounds write when...

CVE-2026-43908 OpenImageIO: Signed integer overflow in ConvertCbYCrYToRGB leads to heap out-of-bounds write in DPX 4:2:2 decoder

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 larg...

CVE-2026-43908

OpenImageIO is affected by a signed 32-bit integer overflow in the pixel-loop index expression i * 3 inside ConvertCbYCrYToRGB(), prior to versions 3.0.18.0 and 3.1.13.0. The overflow can cause a large negative pointer offset in the output buffer, leading to an out-of-bounds write that crashes th...

CVE-2026-43909 OpenImageIO: Signed integer overflow in SwapRGBABytes loop index leads to out-of-bounds read/write in DPX ABGR decoder

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 loop index expression i 4 inside SwapRGBABytes causes the function to compute a large negative...
