Software vendor:
Siemens

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow in the ANSI C OPC UA SDK. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
