Overview

A vulnerability for a remotely exploitable buffer overflow exists
in Gauntlet Firewall by PGP Security.

I. Description

The buffer overflow occurs in the smap/smapd and CSMAP daemons.
According to PGP Security, these daemons are responsible for
handling email transactions for both inbound and outbound email.

On September 04, 2001, PGP Security released a security bulletin
and patches for this vulnerability. For more information, please
see

http://www.kb.cert.org/vuls/id/206723

II. Impact

An intruder can execute arbitrary code with the privileges of the
corresponding daemon. Additionally, firewalls often have trust
relationships with other network devices. An intruder who
compromises a firewall may be able to leverage this trust to
compromise other devices on the network or to make changes to the
network configuration.

III. Solution
