Description Wolfgang Frisch 2020-04-08 06:48:43 UTC
CVE-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.
