    Null Byte Interaction Error (Poison Null Byte)

    Affected versions of this package are vulnerable to Null Byte Interaction Error (Poison Null Byte) due to inadequate validation of domain name labels and lengths in the encodeDomainName and decodeDomainName components. An attacker can cause DNS cache poisoning, bypass domain validation, or trigger excessive memory allocation by supplying specially crafted domain names or malicious DNS responses. This can result in downstream failures, silent truncation of domain names, and parser confusion across different DNS implementations.

    How to fix Null Byte Interaction Error (Poison Null Byte)?

    Upgrade io.netty:netty-codec-dns to version 4.1.133.Final, 4.2.13.Final or higher.
