Description:
Neil Watson has reported a security issue in Ingate Firewall, which may allow PPTP users to bypass certain security restrictions.
The problem is that an active PPTP tunnel is not teared down when the PPTP user is disabled. This allows a blocked PPTP user with an active PPTP tunnel to continue accessing resources until the user disconnects.
The problem has been reported in version 4.1.3 and prior. Other versions may also be affected.
Solution:
Update to version 4.2.2.
