Описание
A flaw was found in open62541. When the Local Discovery Server (LDS) is configured with multicast discovery via the MDNSD backend, an unauthenticated remote attacker can exploit a buffer overflow vulnerability. By sending numerous unique discovery URLs in RegisterServer or RegisterServer2 requests, the attacker can cause the server to crash, leading to a denial of service.
