Summary

Wire's protobuf group-skipping logic did not reject negative lengths before skipping a length-delimited field inside a group. A crafted protobuf payload could cause Wire to throw an unchecked runtime exception during decoding instead of the documented `IOException` / `ProtocolException` failure path. All versions prior to 6.3.0 and 7.x prior to 7.0.0-alpha03 are affected.
