A potential Denial of Service issue in protobuf-java
Summary
A potential Denial of Service issue in protobuf-java was discovered in the parsing procedure for binary data.
Reporter: OSS-Fuzz
Affected versions: All versions of Java Protobufs (including Kotlin and JRuby) prior to the versions listed below. Protobuf "javalite" users (typically Android) are not affected.
Severity
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.
Proof of Concept
For reproduction details, please refer to the oss-fuzz issue that identifies the specific inputs that exercise this parsing weakness.
Remediation and Mitigation
Please update to the latest available versions of the following packages:
- protobuf-java (3.16.1, 3.18.2, 3.19.2)
- protobuf-kotlin (3.18.2, 3.19.2)
- google-protobuf [JRuby gem only] (3.19.2)
