**Description**
The issue is related to errors in processing input data, allowing a remote attacker to cause a denial of service by sending specially crafted BGP update data. This can be achieved via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation). The denial-of-service impact on the network depends on the network's architecture and fault-tolerant design.
