CVE-2021-22569 — Denial of Service of protobuf-java parsing procedure

Affected: Google LLC protobuf-java, Google LLC protobuf-kotlin, Google LLC google-protobuf [JRuby Gem]

An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. We recommend upgrading libraries beyond the vulnerable versions.
