github.com/hamba/avro is vulnerable to Denial Of Service (DoS). The vulnerability exists in the ReadString function of reader.go because config.go does not properly restrict the maximum size of bytes and string types, allowing an attacker to cause an application crash by providing a maliciously crafted string through the Unmarshal() function.
