Package: fiaif
Version: 1.20.0-2
Severity: critical
Tags: security
Justification: root security hole


Facts: 
FIAIF with 3 zones
zone.tun
zone.int
zone.ext

zone.tun is used for a tun device
zone.int is for the internal lan
zone.ext is for the internet

zone.int settings: 
SNAT[0]="EXT ALL 192.168.0.0/27=>0.0.0.0/0"

zone.tun settings:
SNAT[0]="EXT ALL 0.0.0.0/0=>0.0.0.0/0"

What should happen?
Any computer of the tun zone should be natted to the ext one.
A computer in range 192.168.0.0/27 in the int zone should be natted.

With those settings, any computer in any zone gets natted to ext.

It seems to me to be a *big* security problem.
