| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
tls-listener versions prior to 0.10.0
Description
The default configuration of tls-listener makes any public service using
TlsListener::new() vulnerable to a slow-loris DoS attack. A malicious user can open 6.4 TcpStreams a second, sending 0 bytes, and trigger a DoS. This is an instance of a slow-loris attack, which impacts any publicly accessible service using the default configuration of tls-listener.Recommendations
For versions prior to 0.10.0, users are advised to upgrade to version 0.10.0 or later.
As a temporary workaround for users unable to upgrade, consider passing a large value, such as
usize::MAX, as the parameter to Builder::max handshakes to mitigate this issue.Exploit
