The remote host is missing an update to mason announced via advisory DSA 845-1. Christoph Martin noticed that upon configuration mason, which interactively creates a Linux packet filtering firewall, does not install the init script to actually load the firewall during system boot. This will leave the machine without a firewall after a reboot. For the old stable distribution (woody) this problem has been fixed in version 0.13.0.92-2woody1.

For the stable distribution (sarge) this problem has been fixed in version 1.0.0-2.2. For the unstable distribution (sid) this problem has been fixed in version 1.0.0-3. We recommend that you upgrade your mason package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20845-1
