CVE-2023-28831

The OPC UA implementations (ANSI C and C++) in affected products contain an integer overflow vulnerability that could cause the application to run into an infinite loop during certificate validation.

This could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.
