QID 982253: Java (maven) Security Update for io.netty:netty-handler (GHSA-mm9x-g8pc-w292)

The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
