DESCRIPTION

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.
