CVE-2026-43905

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 * buffer_bpp using signed 32-bit arithmetic. When the product exceeds INT_MAX, the result wraps to 0 or a small value. m_buf.resize() allocates an undersized buffer, and subsequent pixel write loops cause heap overflow. Conditional on USE_OPENJPH build flag. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

Summary		(es) OpenImageIO es un conjunto de herramientas para leer, escribir y manipular archivos de imagen de cualquier formato de archivo de imagen relevante para VFX / animación. Antes de 3.0.18.0 y 3.1.13.0, jpeg2000input.cpp:395 calcula el tamaño del búfer como const int bufsize = w * h * ch * buffer_bpp utilizando aritmética de 32 bits con signo. Cuando el producto excede INT_MAX, el resultado se ajusta a 0 o a un valor pequeño. m_buf.resize() asigna un búfer de tamaño insuficiente, y los bucles de escritura de píxeles posteriores causan desbordamiento de montículo. Condicional a la bandera de compilación USE_OPENJPH. Esta vulnerabilidad se corrige en 3.0.18.0 y 3.1.13.0.
