You have received a Security Announcement about traceroute already. An update package in the 6.4-i386 tree got confused with an older version. This older version file has been replaced by the new file under the old name in order to prevent the installation of an older package without the security fixes. I apologize. Here is the corrected advisory: -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: traceroute Announcement-ID: SuSE-SA:2000:041 Date: Monday, October 16th, 2000 16:10 MEST Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 6 SuSE default package: yes Other affected systems: Linux systems using the NANOG traceroute Content of this advisory: 1) security vulnerability resolved: traceroute 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 security problem in the traceroute program as shipped with SuSE Linux distributions is completely different from the one reported on security mailing lists a few days ago (`traceroute -g 1 -g 1') by Pekka Savola . SuSE distributions do not contain this particular traceroute implementation. The problem in our traceroute was discovered independently and reported to us by H D Moore . The problem in the implementation of traceroute that we ship is a format string parsing bug in a routine that can be used to terminate a line in traceroute's output to easily embed the program in cgi scripts as used for web frontends for traceroute. Using a specially crafted sequence of characters on the commandline, it is possile to trick the traceroute program into running arbitrary code as root. If you want to temporarily work around this security vulnerability, you can disable traceroute for normal users by clearing the suid bit on the file /usr/sbin/traceroute: chmod -s /usr/sbin/traceroute . Do not forget to change the respective line in /etc/permissions to read: /usr/sbin/traceroute root.root 755 We have prepared update packages on our ftp server that eliminate the vulnerability in the traceroute program. Note that the traceroute program is contained in the nkita or the nkitb package, depending on the distribution version. Distributions starting with SuSE-6.4 contain the traceroute program in the nkitb package which is not required by the boot process and therefore counts as an additional package. Download the update package from locations described below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. <p> i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/nkitb-2000.10.4-0.i386.rpm 6c8f713a071a96c287942f880cd5919c source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/nkitb-2000.10.4-0.src.rpm c01db9ee70a9ac01cba1bace93cfdd16 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/nkitb-2000.10.4-0.i386.rpm 321b78de11928a3361edf0a044721383 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/nkitb-2000.10.4-0.src.rpm 61aa9e2e4272606d2bd70828a72c957c SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/nkita-2000.10.4-0.i386.rpm 6c5932e4083de6f499e4c77fcadbffc1 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/nkita-2000.10.4-0.src.rpm 9debb8804293384057d69254614a1496 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/nkita-2000.10.4-0.i386.rpm 49269283c6d39a234f61303b2e918413 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/nkita-2000.10.4-0.src.rpm 1cc00eb9b37b37a51fc249db3b51f6e1 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/nkita-2000.10.4-0.i386.rpm 2fe1c6d70fcf1272da95f33ad7ad1010 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/nkita-2000.10.4-0.src.rpm 74d6f2e623b7fcac1b0881b1bfbe0880 <p> SuSE-6.0 Please use the update packages from the 6.1 distribution. <p> Sparc Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/a1/nkitb-2000.10.4-0.sparc.rpm e9bc3512b6182f540e74308c02d81f65 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/nkitb-2000.10.4-0.src.rpm 8fba03e9cef63ae076b10fb61c800e39 <p><p> AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/nkitb-2000.10.4-0.alpha.rpm 7850969c7b3beaf3fd1ce8b2a9246be0 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/nkitb-2000.10.4-0.src.rpm 6e5a964177b6cf87524119c747f0220b SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/nkita-2000.10.4-0.alpha.rpm 6440a6a7da903829cff57a5f8c7cda91 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/nkita-2000.10.4-0.src.rpm 53bf05462378c384e8a46f3c6c368c67 <p><p> PPC Power PC Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/a1/nkitb-2000.10.5-0.ppc.rpm 407d1c6731228f5d3e9addd108d31224 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/nkitb-2000.10.5-0.src.rpm 8fba03e9cef63ae076b10fb61c800e39 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/nkitb-2000.10.4-0.ppc.rpm c432a5b8d37640be6e325ef9603f9cba source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/nkitb-2000.10.4-0.src.rpm edf24c1989c85616d1caf53872e61f17 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: A set of security announcements is following this advisory. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SuSE security discussion.
