CVE-2021-22569: Denial of Service of protobuf-java parsing procedure
First published: Thu Jan 06 2022(Updated: )
A flaw was found in protobuf-java. Google Protocol Buffer (protobuf-java) allows the interleaving of com.google.protobuf.UnknownFieldSet fields. By persuading a victim to open specially-crafted content, a remote attacker could cause a timeout in the ProtobufFuzzer function, resulting in a denial of service.
