-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: bind8 Announcement-ID: SuSE-SA:2000:45 Date: Thursday, November 16th, 2000 16:00 MEST Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4 Vulnerability Type: remote denial of service Severity (1-10): 7 SuSE default package: no Other affected systems: all systems using bind, version 8.2.2 before patchlevel 7 Content of this advisory: 1) security vulnerability resolved: bind8 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 <p> BIND, the Berkeley Internet Name Daemon, versions before 8.2.2p7, has been found vulnerable to two denial of service attacks: named may crash after a compressed zone transfer request (ZXFR) and if an SRV record (defined in RFC2782) is sent to the server. Administrators testing the ZXFR bug should be aware that it can take several seconds after the triggering the bug until the nameserver daemon crashes. SuSE versions 6.0 through 6.4 are affected by these two problems. The bind8 package in SuSE-7.0 is not affected because a different version of bind8 (8.2.3) was used in this distribution. By the release time of the SuSE-7.0 distribution our engineers have determined that the problems we had with stalling zone transfers under some obscure conditions were not present with the 8.2.3 release of the package. Administrators are strongly recommended to upgrade their bind8 package using the provided packages from the sources below. There is a temporary fix for the ZXFR problem (disable zone transfers) but none for the SRV record problem. For the latest information about security vulnerabilities in the bind name server consider the Internet Software Consortium bind security webpage at http://www.isc.org/products/BIND/bind-security.html . To check if your system has the vulnerable package installed, use the command `rpm -q <package name>Ž. If applicable, please choose the update package(s) for your distribution from the URLs listed below and download the necessary rpm files. Then, install the package using the command `rpm -Uhv file.rpmŽ. rpm packages have an internal md5 checksum that protects against file corruption. You can verify this checksum using the command (independently from the md5 signatures below) `rpm --checksig --nogpg file.rpm', The md5 sums under each package are to prove the package authenticity, independently from the md5 checksums in the rpm package format. i386 Intel Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/bind8-8.2.2-139.i386.rpm c6f2242efe722aaa4320010e00ddc080 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/bind8-8.2.2-139.src.rpm ecd26bdf60d7950585649bc638a1d812 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/bind8-8.2.2-139.i386.rpm d3f51528ad2120cd3dc6517c2bc26c0a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/bind8-8.2.2-139.src.rpm 6f1b8c1227d4876389a28d416a952713 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/bind8-8.2.2-139.i386.rpm 4d8a9f4c6e041326929bbdae97c10105 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/bind8-8.2.2-139.src.rpm 83807820676d98687797ffff6f5b425c SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/bind8-8.2.2-139.i386.rpm 1694cf40b5fa41361749297c9cddbca4 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/bind8-8.2.2-139.src.rpm 8c5f727554e12a5aedb96de3db663518 SuSE-6.0 Please use the package from the 6.1 distribution.
