Summary

A vulnerability in the packet processing code of Cisco IOS Software for Cisco
Aironet Access Points could allow an unauthenticated, adjacent attacker to 
retrieve content from memory on an affected device, which could lead to the

by the affected device when the device adds padding to egress packets. An 
attacker could exploit this vulnerability by sending a crafted IP packet to an
affected device. A successful exploit could allow the attacker to retrieve 
content from memory on the affected device, which could lead to the disclosure
of confidential information.
