- The Tungstenite crate before 0.20.1 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). (CVE-2023-43669)
