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 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

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 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)
