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

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
