Frequently Asked Questions
1
What access does an attacker need to exploit this issue?
An attacker can exploit the issue remotely over the network. No authentication or user interaction is required.
2
What is the known impact of successful exploitation?
Successful exploitation can reliably cause a denial of service through a heap overflow during the TCPCLv3 handshake. The available information does not describe confidentiality or integrity impact.
3
Which deployments should be prioritized for investigation?
Prioritize µD3TN v0.15.0 deployments that accept TCPCLv3 connections, since the vulnerable code path is the TCPCLv3 handshake.
