In Firefox this only affects the QUIC header protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is connection failure, but if the connection persists despite the high packet loss it could be possible for a network observer to identify packets as coming from the same source despite a network path change. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1."},{"lang":"es","value":"Llamar a `PK11_Encrypt()` en NSS usando CKM_CHACHA20 y el mismo búfer para entrada y salida puede generar texto plano en un procesador Intel Sandy Bridge. En Firefox, esto solo afecta la función de protección del encabezado QUIC cuando la conexión utiliza el conjunto de cifrado ChaCha20-Poly1305.
