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 TcpStreams 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 prior to 0.10.0. Users are advised to upgrade. Users unable to upgrade may mitigate this by passing a large value, such as usize::MAX as the parameter to Builder::max_handshakes.
tls-listener >= 0.0.0-0, < 0.10.0Upgrade to a patched release:
tls-listener 0.10.0
