Stack-based buffer overflow in the DCERPC inspection engine on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 8.3 before 8.3(2.34), 8.4 before 8.4(4.4), 8.5 before 8.5(1.13), and 8.6 before 8.6(1.3) and the Firewall Services Module (FWSM) 4.1 before 4.1(9) in Cisco Catalyst 6500 series switches and 7600 series routers might allow remote attackers to execute arbitrary code via a crafted DCERPC packet, aka Bug IDs CSCtr21359 and CSCtr27522.
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.
