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."}], "lastModified": "2026-09-29T18:57:32.317", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openimageio:openimageio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4DA6664A-AE08-460C-8866-F8290990DA1D", "versionEndExcluding": "3.0.16.0"}, {"criteria": "cpe:2.3:a:openimageio:openimageio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "72977D24-C839-43ED-896C-5F89FD096023", "versionEndExcluding": "3.1.11.0", "versionStartIncluding": "3.1.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
