In affected versions a well-crafted string passed to avro's `github.com/hamba/avro/v2.Unmarshal()` can throw a `fatal error: runtime: out of memory` which is unrecoverable and can cause denial of service of the consumer of avro. The root cause of the issue is that avro uses part of the input to `Unmarshal()` to determine the size when creating a new slice and hence an attacker may consume arbitrary amounts of memory which in turn may cause the application to crash. This issue has been addressed in commit `b4a402f4` which has been included in release version `2.13.0`. Users are advised to upgrade. There are no known workarounds for this vulnerability."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"hamba","product":"avro","versions":[{"version":"< 2.13.0","status":"affected"}]}]},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","affectedData":[{"vendor":"avro_project","product":"avro","defaultStatus":"unknown","cpes":["cpe:2.3:a:avro_project:avro:*:*:*:*:*:go:*:*"],"versions":[{"version":"0","lessThan":"2.13.0","versionType":"custom","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2024-10-18T17:29:12.659543Z","id":"CVE-2023-37475","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:avro_project:avro:*:*:*:*:*:go:*:*","versionEndExcluding":"2.13.0","matchCriteriaId":"5AC3910F-0EB5-45EE-B590-FE81DEE4ED39"}]}]}],"references":[{"url":"https://github.com/hamba/avro/commit/b4a402f41cf44b6094b5131286830ba9bb1eb290","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/hamba/avro/security/advisories/GHSA-9x44-9pgq-cf45","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/hamba/avro/commit/b4a402f41cf44b6094b5131286830ba9bb1eb290","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/hamba/avro/security/advisories/GHSA-9x44-9pgq-cf45","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Vendor Advisory"]}]}}]}
