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
 (CAN-2003-0965)[2]
 
 2) Cross site scripting vulnerability in the create CGI script
 (CAN-2003-0992)[3]
 
 3) Remote password retrieval vulnerability (CAN-2004-0412)[4]
 As mentioned in the 2.1.5 release announcement[5], previous mailman
 versions are vulnerable to a password retrieval attack which would
 give the attacker the password an user choose when he/she subscribed
 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
 It is recommended that all mailman users upgrade their packages.
