[SNYK HIGH] io.netty:netty-handler Improper Validation of Specified Quantity in Input

[pkfec]

Overview

io.netty:netty-handler is a library that provides an asynchronous event-driven network application framework and tools for rapid development of maintainable high performance and high scalability protocol servers and clients. In other words, Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server.

Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input when validating SSL packets using the native SSLEngine. The SSL_RECORD_HEADER_LENGTH of an incoming packet is not properly checked in the getEncryptedPacketLength() function, allowing attackers to trigger a crash by sending malicious packets.
