Dear SuSE-Team, I am not able to verify the md5 checksum for the package lprold (SuSE 6.1, i386, see security announcement below). After trying out to download the file multiple times from ftp.suse.com, instead of a40c4313756d5b3870fd4bd90e74bc32 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/lprold-3.0.48-0.i386.rpm I get the following checksum: # md5sum lprold-3.0.48-0.i386.rpm 759c041c44631fabf0f1d069a92fc8f1 lprold-3.0.48-0.i386.rpm Has anyone else been able to correcty verify the checksum? I am not going to install the package until the issue is resolved, but disable lpd completely. The md5 checksum for the Alpha package (6.1) seems to be ok. Yours sincerely, Martin Leweling -- Martin Leweling Institut fuer Planetologie, WWU Muenster Wilhelm-Klemm-Str. 10, 48149 Muenster, Germany E-Mail (work): lewelin@uni-muenster.de Original message follows:

Package: lprold < 3.0.48 Date: Tue, 11 Jan 2000 13:01:16 GMT

Affected SuSE versions: all including 6.3 Vulnerability Type: local and remote vulnerabilities SuSE default package: yes Other affected systems: all unix systems using lpr(-old) ______________________________________________________________________________

A security hole was discovered in the package mentioned above. Please update as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s).

Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue.

Please note, that that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________

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. ______________________________________________________________________________
