Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 on 5508 series controllers allows remote attackers to cause a denial of service (buffer leak and device crash) via ARP requests that trigger an ARP storm, aka Bug ID CSCte43508.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
