Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.google.protobuf

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-3171, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.google.protobuf

Analyze the terminal output to locate any version of Protobuf java in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.21.7), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.google.protobuf command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Protobuf java, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary A potential Denial of Service issue in `protobuf-java` core and lite was discovered in the parsing procedure for binary and text format data. Input streams containing multiple instances of non-repeated [embedded messages](http://developers.google.com/protocol-buffers/docs/encoding#embedded) with repeated or unknown fields causes objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses. Reporter: [OSS Fuzz](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48771) Affected versions: This issue affects both the Java full and lite Protobuf runtimes, as well as Protobuf for Kotlin and JRuby, which themselves use the Java Protobuf runtime. ## Severity [CVE-2022-3171](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-3171) Medium - CVSS Score: 5.7 (NOTE: there may be a delay in publication) ## Remediation and Mitigation Please update to the latest available versions of the following packages: protobuf-java (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-javalite (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-kotlin (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-kotlin-lite (3.21.7, 3.20.3, 3.19.6, 3.16.3) google-protobuf [JRuby gem only] (3.21.7, 3.20.3, 3.19.6)
