CVE-2022-41838Public exploitNetwork attack vector

Code execution via mismatched DDS scanline allocation

Published Dec 23, 2022 · Updated Apr 15, 2025

Heap-based buffer overflow in OpenImageIO 2.4.4.2 allows attackers to execute code by supplying a crafted uncompressed DDS file. DDSInput allocates its scanline buffer from channel count and depth, then internal_readimg reads data sized by an unchecked header-derived bytes-per-pixel value. Processing the file through the vulnerable DDS reader exposes the host process to arbitrary code execution or a crash.
