CVE-2004-0459
First published: Thu May 20 2004(Updated: )
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.
