Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Remote Code Execution: The setup scripts pull external NSS packages containing heap buffer overflows (CVE-2021-43527), which could allow remote code execution during signature verification of certificates. Proper package pinning or edge updates are required.

Command Injection: Unvalidated VPN credentials can allow shell metacharacter injection during the evaluation of configuration parameters, leading to unauthorized command execution.

Denial of Service: Use of vulnerable Libreswan versions (prior to 4.6) exposes the IPsec VPN server to remote Denial of Service exploits (CVE-2022-23094).
