CVE-2026-50291OpenImageIO: Segmentation Fault in BmpInput::read_native_scanline (bmpinput.cpp:399)

Description

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to versions 3.0.16.0 and 3.1.11.0, processing a crafted BMP file through oiiotool or an application linked to OpenImageIO can reach BMP palette handling in src/bmp.imageio/bmpinput.cpp with an empty color table. BmpInput::read_native_scanline then performs an invalid palette read while decoding an RLE-compressed scanline, causing a process crash and denial of service. This issue is fixed in versions 3.0.16.0 and 3.1.11.0.
