1. Problem Description

  lprold is the default printer daemon.
  If the hosts.lpd mechanism is used to permit printing to remote hosts,
  this can be circumvented if the attacker controls a DNS server, because
  no double-reverse lookup was done the IP address.
  A second vulnerability involves the manipulating the control file of a
  print job in a way, that statements are sent to sendmail as arguments
  where an attacker could specify a sendmail config file of his own.

2. Impact

  Depending on the hosts.lpd configuration, unauthorized users may use your
  printer (and issue a denial of service attack).
  The second vulnerability leads to an easy root compromise, which can be
  exploited from remote.

3. Solution

  Update the package from our FTP server.
