What the advisory describes

A flaw was found in io.netty/netty-codec-memcache. The Memcache binary protocol codec incorrectly reads `keyLength` and `extrasLength` as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted response. This can lead to frame desynchronization and response smuggling, where one client's data may be inadvertently exposed to another client's response stream in proxy or cache environments.

Source: EUVD (ENISA), in the words of the advisory.
