protobuf-java has a potential Denial of Service issue

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.
