Mandrake CIDR ACLs in version 1.2.9 allow access even to files and directories that are otherwise specifically denied.

Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           proftpd
 Advisory ID:            MDKSA-2004:041
 Date:                   April 30th, 2004

 Affected versions:	 10.0
 ______________________________________________________________________

 Problem Description:

 A portability workaround that was applied in version 1.2.9 of the
 ProFTPD FTP server caused CIDR based ACL entries in "Allow" and "Deny"
 directives to act like an "AllowAll" directive.  This granted FTP
 clients access to files and directories that the server configuration
 may have been explicitly denying.
 
 This problem only exists in version 1.2.9 and has been fixed upstream.
 A patch has been applied to correct the problem.
