DESCRIPTION:
Some vulnerabilities have been discovered in ActiveFax (ActFax),
which can be exploited by malicious users and malicious people to
compromise a user's system.

1) A boundary error when processing the FTP "RETR" command can be
exploited to cause a stack-based buffer overflow by sending a "RETR"
command with an overly long parameter to the FTP server.

2) A boundary error within the LPD/LPR server can be exploited to
cause a stack-based buffer overflow by sending a specially crafted
command to the server.

The vulnerabilities are confirmed in version 4.25 Build 0221. Other
versions may also be affected.

SOLUTION:
Restrict access to trusted users. Restrict access to the affected
services using a firewall.
