Overview

Affected versions of this package are vulnerable to Use of Less Trusted Source due to improper validation of the interaction between DisableForwarding and PermitTunnel settings. An attacker can enable unauthorized tunneling by exploiting a misconfiguration where DisableForwarding does not override PermitTunnel. This is only exploitable if both DisableForwarding=yes and PermitTunnel=yes are set simultaneously.
