Descriptions

The Clear Channel Assessment (CCA) algorithm in the IEEE 802.11 wireless protocol, when using DSSS transmission encoding, allows remote attackers to cause a denial of service via a certain RF signal that causes a channel to appear busy (aka "jabber"), which prevents devices from transmitting data.

El algoritmo de identificicación de canal vacio (Clear Channel Assessment - CCA) en el protocolo inalámbrico IEEE 802.11, cuando usa codificación de trasmisión de codificación DSSS, permite a atacantes remotos causar una denegación de servicio mediante ciertas señales de RF que causan que el canel aparezca ocupado ("jabber"), lo que impida que los dispositivos reciban datos.
