Stack-based buffer overflow in the Profinet DCP protocol implementation on the Siemens Scalance S Security Module firewall S602 V2, S612 V2, and S613 V2 with firmware before 2.3.0.3 allows remote attackers to cause a denial of service (device outage) or possibly execute arbitrary code via a crafted DCP frame.
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.
