-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: cups Announcement-ID: SuSE-SA:2002:005 Date: Saturday, Feb 23st 2002 09:10 MET Affected SuSE versions: 7.1, 7.2, 7.3 Vulnerability Type: remote privilege escalation Severity (1-10): 5 SuSE default package: no Other affected systems: all systems running CUPS Content of this advisory: 1) security vulnerability resolved: CUPS bufferoverflow in IPP problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The well known Common Unix Printing System (CUPS) was found vulnerable to a buffer overflow in the Internet Printing Protocol (IPP) handling code. The buffer overflow could be exploited by a remote attacker as long as their IP address is allowed to connect to the CUPS server. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. After updateing the packages run "rclpd restart" as root to start the new daemon. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-1.1.10-81.i386.rpm bfb52a55305ac12880b5e59410205a6e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/cups-1.1.10-81.src.rpm e3d276cb505eaa1bf35946b5c1029562 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-client-1.1.10-81.i386.rpm 527eeb095abeb0ee0cad95f028a8222b SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-libs-1.1.10-81.i386.rpm 9a125db90716f71b4fa31cf2ba4180a8 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/d3/cups-devel-1.1.10-81.i386.rpm d8457f2c62e7a85e927b615570efa82b SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/cups-1.1.6-103.i386.rpm 9a6c6b3fcd1dea6504121b76de1615b5 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/cups-1.1.6-103.src.rpm 92c0fc63d6b9c6c299583868f69ac649 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/d3/cups-devel-1.1.6-103.i386.rpm a0ed0a207040b6aa6b8080d7e146ce04 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/cups-1.1.6-102.i386.rpm 488317348075ae50f0d5f5bd9e82b247 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/cups-1.1.6-102.src.rpm 54f3b1bcb3cc727dfcf05514d84c402d SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d3/cups-devel-1.1.6-102.i386.rpm 6019620534415dd4d09681583ee627a1 Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-1.1.10-34.sparc.rpm 7777fb032e1c2b45956db2d3ccf9b3c3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/cups-1.1.10-34.src.rpm 91684561da7f476055c71239b61c549b SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-client-1.1.10-34.sparc.rpm 8badff242e1903d7f812bafb0e6a1831 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-libs-1.1.10-34.sparc.rpm 355221f9ca9c435a24251915b3384ea2 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/d3/cups-devel-1.1.10-34.sparc.rpm 60daf45ca8a75237421c8abd27c9f433 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n2/cups-1.1.6-37.sparc.rpm 063b7953d50ad4b4958541bfaccd270c source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/cups-1.1.6-37.src.rpm d5d5e4bf719ab2eca49cadc9708e0ff3 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/d3/cups-devel-1.1.6-37.sparc.rpm 2cbd702f7d978a098ce9c84e3b1cc7ff AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n2/cups-1.1.6-33.alpha.rpm 7188e40aac0c097095c2df088a93265d source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/cups-1.1.6-33.src.rpm ac122fe5b1305bab6a8c5904699d4bd5 SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/d3/cups-devel-1.1.6-33.alpha.rpm ae6685e65e7db1b9afe276d51d6da51a PPC PowerPC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-1.1.10-60.ppc.rpm 99aa8fcf0f21d5799931953c90435d72 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/cups-1.1.10-60.src.rpm 6e0b6c9e04eb7167b3585aebbc0deb29 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-client-1.1.10-60.ppc.rpm 61f807924b16930166d711c1da8a4cc0 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-libs-1.1.10-60.ppc.rpm 090132d0ae790027382c88a9b331fa9e SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/d3/cups-devel-1.1.10-60.ppc.rpm f211da7b5dc400c8e087a6ef8178afd5 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n2/cups-1.1.6-47.ppc.rpm 52c247f3cbf4836dacec7a767a4fe3c7 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/cups-1.1.6-47.src.rpm 1937730cf78b1c658b430e9525084a93 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/d3/cups-devel-1.1.6-47.ppc.rpm c906d4106d30f1e84133e8d45a857b2d ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - squid A heap overflow in squid's URL constructing functions is fixed and new packages are currently being built. - ucd-snmpd The UCD snmpd contains various security releated bugs. We are currently reviewing the code and available fixes to ensure they all get fixed. Patches will be available as soon as possible. It is strongly recommended to filter SNMP (TCP and UDP packets with destination of port 161) traffic. - hanterm/wmtv The recently reported vulnerabilities in hanterm and wmtv do not affect SuSE installations because they are not installed setuid or setgid. - cipe We are about to prepare kernel update packages that fix a DoS problem in the kernel modules for the cipe encrypted tunneling software. ______________________________________________________________________________ 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.
