DESCRIPTION
Mailman[1] is a mailing list manager.

This update fixes the following vulnerabilities for Conectiva Linux
9:

1) Cross site scripting vulnerability in the admin CGI script

2) Cross site scripting vulnerability in the create CGI script
(CAN-2003-0992)[3]

to a mailing list.

For Conectiva Linux 8, the following vulnerability has been fixed:

- CAN-2003-0991[6]: denial of service vulnerability caused by
specific mail messages which would crash mailman.


SOLUTION
