{"id":"CVE-2023-25656","summary":"notation-go has excessive memory allocation on verification","details":"notation-go is a collection of libraries for supporting Notation sign, verify, push, and pull of oci artifacts. Prior to version 1.0.0-rc.3, notation-go users will find their application using excessive memory when verifying signatures. The application will be killed, and thus availability is impacted. The problem has been patched in the release v1.0.0-rc.3. Some workarounds are available. Users can review their own trust policy file and check if the identity string contains `=#`. Meanwhile, users should only put trusted certificates in their trust stores referenced by their own trust policy files, and make sure the `authenticity` validation is set to `enforce`.","aliases":["GHSA-87x9-7grx-m28v","GO-2023-1589"],"modified":"2026-08-12T03:51:11.391361907Z","published":"2023-02-20T00:00:00Z","related":["CGA-cx4p-wvhc-q6q3"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25656.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-770"]},"references":[{"type":"WEB","url":"https://github.com/notaryproject/notation-go/releases/tag/v1.0.0-rc.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25656.json"},{"type":"ADVISORY","url":"https://github.com/notaryproject/notation-go/security/advisories/GHSA-87x9-7grx-m28v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25656"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/notaryproject/notation-go","events":[{"introduced":"de8b7ddaa5b22c6b4c40924ade50d89bfb813a25"},{"fixed":"de8b7ddaa5b22c6b4c40924ade50d89bfb813a25"}],"database_specific":{"extracted_events":[{"introduced":"1.0.0-rc.3"},{"last_affected":"1.0.0-rc.3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["1.0.0-rc.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-25656.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
