CVE-2023-43669 Information

Description

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).
