Descriptions

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).

El Tungstenite crate anterior a la versión 0.20.1 para Rust permite a atacantes remotos provocar una denegación del servicio (de minutos de consumo de la CPU) a través de una longitud excesiva de un encabezado HTTP en el handshake del cliente. La longitud afecta tanto a cuántas veces se intenta un análisis (por ejemplo, miles de veces) y la cantidad promedio de datos para cada intento de análisis (por ejemplo, millones de bytes).
