Buffer overflow in CCEServer (aka the central communications component) in Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, allows remote attackers to cause a denial of service via a crafted packet.
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.
