### Overview The line printer daemon enables various clients to share printers over a network. There exists a buffer overflow vulnerability in this daemon that permits remote execution of arbitrary commands with elevated privileges. ### Description There is a buffer overflow in several implementations of in.lpd, a BSD line printer daemon. An intruder can send a specially crafted print job to the target and then request a display of the print queue to trigger the buffer overflow. The intruder may be able use this overflow to execute arbitrary commands on the system with superuser privileges. The line printer daemon must be enabled and configured properly in order for an intruder to exploit this vulnerability. This is, however, trivial as the line printer daemon is commonly enabled to provide printing functionality. In order to exploit the buffer overflow, the intruder must launch his attack from a system that is listed in the "/etc/hosts.equiv" or "/etc/hosts.lpd" file of the target system. --- ### Impact An intruder can remotely execute arbitrary commands on the system with the privileges of the line printer daemon, usually root or a superuser. --- ### Solution Apply a patch, if available, from your vendor. --- Disable the line printer daemon if there is not a patch available from your vendor. --- ### Vendor Information 274043 Filter by status: All Affected Not Affected Unknown Filter by content: __Additional information available __Sort by: Status Alphabetical Expand all **Javascript is disabled.

Technical Details ================= http://msgs.securepoint.com/cgi-bin/get/bugtraq0108/259.html Solutions and Workarounds ========================= NetBSD 1.3 and later install with lpd disabled by default. A system is vulnerable to this security hole only if it is running /usr/sbin/lpd, and access to lpd is allowed by entries in /etc/hosts.lpd. Updating the binary for safety is recommended. Quick workaround: If you are running /usr/sbin/lpd, and you do not need it, stop it. If you have /etc/hosts.lpd which is open to everyone, you will want to tighten the setup so that no malicious parties can access your remote printer. Solutions: * NetBSD -current, 1.5, 1.5.1, 1.5.2: Systems running NetBSD-current dated from before 2001-08-28 should be upgraded to NetBSD-current dated 2001-08-28 or later.

Although lpd is part of the IRIX print.sw.bsdlpr system and is not installed by default, if it is installed it runs with root privileges by default on all current IRIX versions. Issue #2: lpsched Last Stage of Delirium has reported vulnerabilities in the lpsched program which allow remote attackers with sufficient control of their remote network to obtain 'root' and 'lp' privileges remotely. lpsched is installed by default on all current IRIX versions. Issue #3: lpstat Last Stage of Delirium has reported a vulnerability in the lpstat command in the way it loads and executes code from user supplied net-type shared library objects. When appropriately exploited it can lead to a local root compromise on a vulnerable system. lpstat is installed by default on all current IRIX versions. \- -------------- \- --- Impact --- \- -------------- lpsched and lpstat are installed by default on IRIX. lpd is part of the optional print.sw.bsdlpr subsystem and is not installed by default on IRIX. A local user account on the vulnerable system is not required in order to exploit these vulnerabilities. Vulnerable systems can be exploited remotely over an untrusted network. These vulnerabilities can lead to a root compromise. ISS X-Force reported the lpd vulnerability: http://xforce.iss.net/alerts/advise80.php The lpd vulnerability was also reported by CERT® Advisory CA-2001-15: http://www.cert.org/advisories/CA-2001-15.html The lpd vulnerability was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2001-0353 Last Stage of Delirium reported the lpstat and lpsched vulnerabilities: http://www.lsd-pl.net/files/get?IRIX/irx_lpstat2 http://www.lsd-pl.net/files/get?IRIX/irx_lpsched http://www.lsd-pl.net/files/get?IRIX/irx_lpsched2 These vulnerabilities have been publicly discussed in Usenet newsgroups and security mailing lists. \- ---------------------- \- --- Recommendation --- \- ---------------------- SGI has investigated the issues and recommends the following steps for neutralizing the exposures. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. This issue has been corrected in future releases of IRIX. \- -------------------------- \- --- Temporary Solution --- \- -------------------------- Although patches are available for this issue, it is realized that there may be situations where installing the patches immediately may not be possible. The steps below can be used to remove the print.sw subsystems to prevent exploitation of these vulnerabilities until patches can be installed. ================= **** WARNING **** ================= These steps will disable printing capabilities. 1) Become the root user on the system. % /bin/su - Password: # 2) Stop the printing services # /etc/init.d/bsdlpr stop # /etc/init.d/lp stop 3) Use the "versions" command to remove the printing subsystems: # versions remove print.sw.* 5) Return to previous level. # exit % 6) It is not necessary to reboot the system. \- ---------------- \- --- Solution --- \- ---------------- OS Version Vulnerable?

Due to missing bounds checks in the lockfile processing function, internal buffers may overflow. Bounds checks have been added to fix that problem. Additionally the SuSE Security Team uncovered other security releated bugs in lpd while analyzing lpd source after receiving the X-Force advisory. These bugs allows users on machines listed in /etc/hosts.lpd or /etc/hosts.equiv to chown any file on the system running lpd to any user. In order to trigger any of the fixed bugs (including the overflow) the attackers machine must be listed in one of these two access-files and the attacker usually needs root on these machines due to the privileged-port requirement. Please download the packages and verify them as described in section 3. After successful authentication you can update your packages with the command `rpm -Uhv file.rpm'. As root invoke the command "/etc/rc.d/lpd stop" to shutdown the old lpd daemon and "/etc/rc.d/lpd start" afterwards to start the patched daemon. i386 Intel Platform: SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/lprold-3.0.48-272.i386.rpm 23b8251411a557563cb314102f405d31 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/lprold-3.0.48-272.src.rpm ff590e05f2a7c85e9d234bd32d12b13a SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n1/lprold-3.0.48-275.i386.rpm b6efc424262ec9aaa39ac84f230b3df2 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/lprold-3.0.48-275.src.rpm 5a95de121c7520bf33620dddbfdda611 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/lprold-3.0.48-275.i386.rpm 10792a921880048970f40470f1b94330 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/lprold-3.0.48-275.src.rpm 094b06515dfd865c6dffedf70de5e6cc SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/lprold-3.0.48-275.i386.rpm da1b920d23694a807f91c74301b47ced source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/lprold-3.0.48-275.src.rpm c2c45f04a2d44e374689346f488e8c52 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/lprold-3.0.48-275.i386.rpm 8f7c5538e878f197de1e6dacdb6a8479 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/lprold-3.0.48-275.src.rpm d13f74f6449ee40b98b2ed0e42e9d2ec Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n1/lprold-3.0.48-216.sparc.rpm 78a947db44bc4a41cb33eee1b931b99e source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/lprold-3.0.48-216.src.rpm 2c873632eaa6f01efb45cba3f1308cd3 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/lprold-3.0.48-216.sparc.rpm 45320846ee6143fdfc27a7d578f630bd source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/lprold-3.0.48-216.src.rpm 1be6f31b6924f81fb965b0dce053f6cb AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n1/lprold-3.0.48-215.alpha.rpm 94af7565e8920cdce6e1e7c51f562fba source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/lprold-3.0.48-215.src.rpm 0757d322145ef6c2179c8e31b1169cd2 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/lprold-3.0.48-215.alpha.rpm 3c6a2b2b21fcc1b94974aca6c5930e98 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/lprold-3.0.48-215.src.rpm 0222dec4d0287b9f1f267b86e8e8a4dd SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/lprold-3.0.48-215.alpha.rpm f4c618b43a95bd94ed679c1c2119a7aa source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/lprold-3.0.48-215.src.rpm 0430ec91e7515d79326ed16f492ea60e SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/lprold-3.0.48-215.alpha.rpm 68a8b9a26e17ed5183b8385be349c6a9 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/lprold-3.0.48-215.src.rpm 582d925d8328f79bc566dddcc62f763b Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n1/lprold-3.0.48-200.ppc.rpm 3c16c1975b8f9dae3ccfb67dd5f462db source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/lprold-3.0.48-200.src.rpm 37b0d3534e39273e158eba42f75f8e31 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/lprold-3.0.48-200.ppc.rpm d0e5a115d8991e711ef75fc8b06e1d97 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/lprold-3.0.48-200.src.rpm e4d589e9225365b103b502a26d0fd73f SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/lprold-3.0.48-200.ppc.rpm f8e7557f995388564f98e9bae4708e4e source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/lprold-3.0.48-200.src.rpm 78a647beeaf5a5541cb15aa6435ba65e ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: \- sftp/openssh: Our last announcement SuSE-SA:2001:032 about WindowMaker claimed that the openssh packages on SuSE distributions do not contain the sftp-server as described by Peter W on the bugtraq mailing list. This is wrong: The program is indeed included on all recent openssh packages of SuSE Linux distributions, starting with SuSE Linux 6.4 where the openssh package appeared first. We will provide fixes for the distributions 6.4 through 7.2 as soon as possible on our ftp server (ftp.suse.de for 6.4-7.0, ftp.suse.com for 7.1 and newer) and announce these fixes in the section 2) of an upcoming security announcement. Please note that this error has been corrected shortly before the release of the upcoming SuSE Linux 7.3 which will arrive in the stores by the end of this week. We apologize for this error (Roman Drahtmueller, SuSE Security). \- squid Malformed requests on the client side can cause the squid proxy server to die, resulting in a denial of service attack that can be launched from the internal network if squid is used at the edge of an internal network to proxy requests to the internet. We are in the process of testing the update packages that are available on the ftp server shortly. SuSE Security will issue a dedicated announcement for this issue shortly. \- devfs/kernel SuSE Linux ships the userspace utilities for the use of the devfs filesystem in the linux kernel, but neither the utilities nor the filesystem interface for device files itself have been used in SuSE Linux up to date. The decision to not actively use devfsd in the distribution framework is based on security considerations. For these reasons, SuSE products are not susceptible to the lately found security problems in the devfs implementation. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information \- Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security@suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig to verify the signature of the package, where is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build@suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . \- SuSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com \- general/linux/SuSE security discussion.
