Heap-based buffer overflow in Cisco Unified IP Phone 7940, 7940G, 7960, and 7960G running SIP firmware might allow remote SIP servers to execute arbitrary code via a crafted challenge/response message.
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.
