QID 995366: Rust (Rust) Security Update for tungstenite (GHSA-9mcr-873m-xcxp)

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).

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
