Attackers can supply a crafted Cineon file with a huge declared width that wraps the size calculation to zero, so UnPackPacked reads past a 4-byte buffer and crashes the application.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8},"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-190"],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/blob/v3.0.19.0/src/cineon.imageio/libcineon/Codec.cpp#L79-L82","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/07e3c3e0373551c57e7d8e01353deaa4b3646613","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5567","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5568","https://www.vulncheck.com/advisories/openimageio-before-3.0.20.0-3.1-x-before-3.1.15.0-and-3.2-x-before-3.2.0.3-beta1-cineon-reader-heap-out-of-bounds-read"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-113681","score":0.00165,"percentile":0.05629,"date":"2026-10-25"},"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).
