HIGHCVE-2020-11612

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.

Affected: >= 4.1.0, < 4.1.46
Fixed in: 4.1.46
