An attacker who has compromised a registry and added a high number of signatures to an artifact can cause denial of service of services on the machine, if a user runs notation verify command on the same machine. The problem has been fixed in the release v1.0.0-rc.6. Users should upgrade their notation packages to v1.0.0-rc.6 or above. Users unable to upgrade may restrict container registries to a set of secure and trusted container registries.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-400"],"references":["https://github.com/notaryproject/notation/releases/tag/v1.0.0-rc.6","https://github.com/notaryproject/notation/security/advisories/GHSA-rvrx-rrwh-r9p6","https://github.com/notaryproject/notation/releases/tag/v1.0.0-rc.6","https://github.com/notaryproject/notation/security/advisories/GHSA-rvrx-rrwh-r9p6"],"products":["notaryproject:notation-go"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-33958","score":0.00485,"percentile":0.41807,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rvrx-rrwh-r9p6","url":"https://osv.dev/vulnerability/GHSA-rvrx-rrwh-r9p6","summary":"Notation's default `maxSignatureAttempts` in `notation verify` enables an endless data attack","modified":"2026-09-10T03:50:02.360601255Z","packages":[{"ecosystem":"Go","name":"github.com/notaryproject/notation","purl":"pkg:golang/github.com/notaryproject/notation","ranges":["<1.0.0-rc.6"],"fixed":["1.0.0-rc.6"]}]},{"id":"GO-2023-1831","url":"https://osv.dev/vulnerability/GO-2023-1831","summary":"Notation's default `maxSignatureAttempts` in `notation verify` enables an endless data attack in github.com/notaryproject/notation","modified":"2026-03-03T04:51:27.726121Z","packages":[{"ecosystem":"Go","name":"github.com/notaryproject/notation","purl":"pkg:golang/github.com/notaryproject/notation","ranges":["<1.0.0-rc.6"],"fixed":["1.0.0-rc.6"]}]}],"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).
