An exploit was publicly released by FrSIRT for crafting the arp requests needed to exploit the vulnerability described at Cisco. As a reminder this vulnerability is related to resource exhaustion and consequently a Denial of Service condition due to arp requests.
If you have not taken measures to protect your Cisco Aironet Access Points, now would be a good time to start planning the upgrades or implement one of the workarounds in the Cisco advisory.
