netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

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 memor...
