Buffer overflow in Cisco Unified IP Phone 7940, 7940G, 7960, and 7960G running SCCP and SIP firmware might allow remote attackers to execute arbitrary code via a crafted DNS response.
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.
