| Doc Text: |
A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS (Transport Layer Security) ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service (DoS) due to excessive memory consumption. The issue occurs in the `SslClientHelloHandler.decode()` method when processing the TLS handshake length.
