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.
