CVE-2024-28854 is a high-severity flaw (CVSS 7.5) affecting tls-listener. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

tls-listener is a rust lang wrapper around a connection listener to support TLS. With the default configuration of tls-listener, a malicious user can open 6.4 `TcpStream`s a second, sending 0 bytes, and can trigger a DoS. The default configuration options make any public service using `TlsListener::new()` vulnerable to a slow-loris DoS attack. This impacts any publicly accessible service using the default configuration of tls-listener in versions
