Overview

io.netty:netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) attacks. The SSLv3 protocol uses nondeterministic CBC padding, which makes it easier for Man-in-the-Middle (MitM) attackers to obtain cleartext data via a padding-oracle attack. This is also known as the POODLE vulnerability.
