Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted fits stream containing consecutive 2880-byte header blocks without the mandatory end keyword makes fitsinput::read_fits_header() call itself without a depth bound. repeated recursive parsing exhausts the application stack, resulting in denial of service. The affected implementation is identified by src/fits.imageio/fitsinput.cpp, FitsInput::read_fits_header(), END keyword, and 2880-byte FITS header blocks, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.","state":0,"publishedAt":"2026-09-18T15:34:19.593+00:00","modifiedAt":"2026-09-24T20:55:49.717+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenImageIO","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AcademySoftwareFoundation\",\n                    \"product\": \"OpenImageIO\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.0.20.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.1.0.0, < 3.1.15.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.2.0.0-dev, < 3.2.0.3-beta1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-xvwr-x6ch-v2fq","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5248","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/b0de7d40d06eb4abc7ef14c1321a1a2a976d8c1c","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.20.0","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.15.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59156","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59156","identifiers":["CVE-2026-59156"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
