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).
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| snapview:tungstenite | snapview tungstenite | le | 0.20.0 |
