Affected packages

• Maven io.netty:netty-handler: >= 4.1.0, < 4.1.46 → fixed in 4.1.46

Description

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.
