A denial-of-service vulnerability exists in the Ethernet/IP server functionality of Rockwell Automation RSLinx Classic 2.57.00.14 CPR 9 SR 3. A specially crafted network request can lead to a denial of service. An attacker can send a sequence of malicious packets to trigger this vulnerability.
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
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.
