"details": "## Summary\n\nA potential Denial of Service issue in protobuf-java was discovered in the parsing procedure for binary data.\n\nReporter: [OSS-Fuzz](https://github.com/google/oss-fuzz)\n\nAffected versions: All versions of Java Protobufs (including Kotlin and JRuby) prior to the versions listed below. Protobuf \"javalite\" users (typically Android) are not affected.\n\n## Severity\n\n[CVE-2021-22569](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22569) **High** - CVSS Score: 7.5, An implementation weakness in how unknown fields are parsed in Java. A small (~800 KB) malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated GC pauses.\n\n## Proof of Concept\n\nFor reproduction details, please refer to the oss-fuzz issue that identifies the specific inputs that exercise this parsing weakness.\n\n## Remediation and Mitigation\n\nPlease update to the latest available versions of the following packages:\n\n- protobuf-java (3.16.1, 3.18.2, 3.19.2) \n- protobuf-kotlin (3.18.2, 3.19.2)\n- google-protobuf [JRuby gem only] (3.19.2) \n",
