io.netty/netty-handler: Netty: SNI Routing Bypass via Fragmented TLS ClientHello Causing Fallback to Default SslContext

A flaw was found in Netty, an asynchronous, event-driven network application framework. An unauthenticated remote attacker can exploit fragmented Transport Layer Security TLS ClientHello messages to bypass the Server Name Indication SNI routing mechanism. This forces a fallback to a less secure...
