Summary
OpenImageIO: JPEG2000 (OpenJPH) signed integer overflow in buffer allocation
Details

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, jpeg2000input.cpp:395 computes buffer size as const int bufsize = w * h * ch * bufferbpp using signed 32-bit arithmetic. When the product exceeds INTMAX, the result wraps to 0 or a small value. mbuf.resize() allocates an undersized buffer, and subsequent pixel write loops cause heap overflow. Conditional on USEOPENJPH build flag. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
