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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-125"],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/91500ed58ce927b7e710c6bbc3b7f795bb0791b5","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/be984856e315e0a82cd866745b544c8c4cb8bd45","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/ee3370d004d5895554239b4302c59eedb721f086","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5030","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.16.0"],"products":["openimageio:openimageio"],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-50291","score":0.00199,"percentile":0.09692,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
