A flaw was found in NetworkManager-iodine, the iodine VPN plugin for NetworkManager. A local unprivileged user can exploit a vulnerability in how the 'nameserver' setting is processed when establishing an iodine VPN connection. By embedding shell metacharacters (special characters that can execute commands) in the 'nameserver' value, an attacker can inject and execute arbitrary commands. These commands run with root privileges before the application drops its elevated permissions, leading to local privilege escalation.
