SUSE: Security Advisory for lprold 3.0.48 Critical: Remote Access

A security hole was discovered in the package lprold < 3.0.48.. -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement 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 FTPserver. ______________________________________________________________________________ Please verify these md5 checksums of the updates before installing: (For SuSE 6.0, please use the 6.1 updates) 72c9261e00024b3388246c900c8a95e5 ce0e2ff49e11e15db2f29607867d49e0 /6.3/n1/lprold-3.0.48-4.alpha.rpm 6340bd651729c535cc2ae2ff0e080a47 af82f4fea307acb584e38a0696ad247b 3404fb4e939203c8b8145e7880035869 ______________________________________________________________________________ You can find updates on our ftp-Server: for Intel processors for Alpha processors or try the following web pages for a list of mirrors: https://www.suse.com/de-de/ Our webpage for patches: https://www.suse.com/de-de/ Our webpage for security announcements: https://www.suse.com/de-de/ If you want to report vulnerabilities, please contact This email address is being protected from spambots.
