CVE-2021-22569
HIGHprotobuf-java < 3.16.1 - Denial of Service via UnknownFieldSet Field Interleaving
Title source: llmDescription
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.
