NVD Description

Note: Versions mentioned in the description apply only to the upstream libwebsockets package and not the libwebsockets package as distributed by RHEL.

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.
