| Doc Text: |
A flaw was found in protobuf. A remote attacker can exploit this denial-of-service (DoS) vulnerability by supplying deeply nested `google.protobuf.Any` messages to the `google.protobuf.json_format.ParseDict()` function. This bypasses the intended recursion depth limit, leading to the exhaustion of Python’s recursion stack and causing a `RecursionError`, which results in a denial of service.
