Problem description

A bug in the authentication code of hfaxd has been fixed that allowed attackers to gain unauthorized access to the fax system by guessing the content of the hosts.hfaxd file.

  192.168.0
  username:uid:pass:adminpass

will no longer work after this update. Such entries should be changed into

  username@:uid:pass:adminpass
