CVE-2026-43905 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, 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.
A heap buffer overflow vulnerability has been identified in OpenImageIO versions prior to 3.0.18.0 and 3.1.13.0. The issue arises in the JPEG2000 input processing, specifically in the 'jpeg2000input.cpp' file. The vulnerability is triggered by a signed integer overflow in buffer size calculations, which allows for the allocation of undersized buffers. This flaw can be exploited by writing pixels into the undersized buffer, causing a heap overflow. The vulnerability is present only in builds in which the 'USE_OPENJPH' flag is enabled.
Users can upgrade to OpenImageIO versions 3.0.18.0 or 3.1.13.0 to address this vulnerability.
