CVE-2023-43669

The Tungstenite crate through 0.20.0 for Rust allows remote attackers to cause a
denial of service (minutes of CPU consumption) via an excessive length of an
HTTP header in a client handshake. The length affects both how many times a
parse is attempted (e.g., thousands of times) and the average amount of data for
each parse attempt (e.g., millions of bytes).
