A vulnerability in the parsing of ethernet frames in AOS-8 Instant and AOS 10 could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could allow an attacker to potentially disrupt network services and require manual intervention to restore functionality.
The product does not properly control the allocation and maintenance of a limited resource.
Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
