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.
