This requires kadmind to run to be effective. - CVE-2007-2442, CVE-2007-2443: Additionally two bugs in the RPC library of kadmind were fixed that can lead to remote system compromise. Note that third-party applications using this RPC library are vulnerable too. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes None. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/krb5-1.5.1-23.6.i586.rpm dc2fa8951dada9f5682fe449dc385e2d ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/krb5-devel-1.5.1-23.6.i586.rpm dd2d611d86a420e45f5cacce9d7fdec1 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/krb5-server-1.5.1-23.6.i586.rpm 5daa3fedc4198ebb7b4d0a8127bed8ed SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/krb5-1.4.3-19.22.i586.rpm 09da59a0aaafd6c8d22321752f2c38d3 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/krb5-devel-1.4.3-19.22.i586.rpm 0840fcc71f5b4e97beb835e0e25dedbc ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/krb5-server-1.4.3-19.22.i586.rpm 9d23419758f2b0a69ba143dbacbc9f0a SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/krb5-1.4.1-5.7.i586.rpm 32b71e707e4ec85b0eee500de51a89cf ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/krb5-devel-1.4.1-5.7.i586.rpm f71c6582dcb3a74a804a4143ff6f48c3 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/krb5-server-1.4.1-5.7.i586.rpm 22b2f9c5cc94918a58c8c5e1b4d6296d Power PC Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/krb5-1.5.1-23.6.ppc.rpm cdf7854a981af8b5b9e4ad5d0eca9c7d ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/krb5-devel-1.5.1-23.6.ppc.rpm 5aba32af56d726c3616cc4260a69a848 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/krb5-server-1.5.1-23.6.ppc.rpm a1ab8842ba74f4b2a3e2cba56d730556 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/krb5-1.4.3-19.22.ppc.rpm aa13e756476c571bdb9d1f909ffdd2d9 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/krb5-devel-1.4.3-19.22.ppc.rpm c121580b3e9392f8de76efda8d5dd551 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/krb5-server-1.4.3-19.22.ppc.rpm aabf1f7df56922b01d67213af2cfc0af SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/krb5-1.4.1-5.7.ppc.rpm 069361f8698af89dc366bf3d2cdf7239 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/krb5-devel-1.4.1-5.7.ppc.rpm e440e4b49b571b8bf9ebf0f9200d29c3 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/krb5-server-1.4.1-5.7.ppc.rpm 4188e3334beceefce3cab6aa8429a16c x86-64 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/krb5-1.5.1-23.6.x86_64.rpm edff62bb110662ee8a16f51b69c684c2 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/krb5-32bit-1.5.1-23.6.x86_64.rpm af81d30ce34ee7c0c708a8c0f17d81a5 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/krb5-devel-1.5.1-23.6.x86_64.rpm 7d204e67fa211a528acedd6980925686 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/krb5-devel-32bit-1.5.1-23.6.x86_64.rpm 8036b0e78e1fea05e895b7d2c5717538 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/krb5-server-1.5.1-23.6.x86_64.rpm 14238f108e2375205961a73ec15ecbde SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/krb5-1.4.3-19.22.x86_64.rpm 0c46b69cf856956753908711a391ca3c ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/krb5-32bit-1.4.3-19.22.x86_64.rpm cd9562c71d1439f9ea1b7fd29b2a2a15 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/krb5-devel-1.4.3-19.22.x86_64.rpm 624a0d8362e07050d705642f12e6109e ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/krb5-devel-32bit-1.4.3-19.22.x86_64.rpm 30cd873aa47a0006d5e402e2280d311f ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/krb5-server-1.4.3-19.22.x86_64.rpm 6149c3d8873ebbdf0549f74eabd61a0e SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/krb5-1.4.1-5.7.x86_64.rpm eaf8552be5695919d2d7a058339c4d1f ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/krb5-32bit-1.4.1-5.7.x86_64.rpm 146f189e550f82bc987cde96a0b13086 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/krb5-devel-1.4.1-5.7.x86_64.rpm 5bd145009778a85a0e8d26f58cf976c6 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/krb5-devel-32bit-1.4.1-5.7.x86_64.rpm 21418e68ed403d5bc822e8e31473bc57 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/krb5-server-1.4.1-5.7.x86_64.rpm 2c55efe366234d32d547c85ffe3e78a2 Sources: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/src/krb5-1.5.1-23.6.src.rpm e3a6f207ca990afd58afec40b3b08aea SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/krb5-1.4.3-19.22.src.rpm a29ba835ba013e45102b136d7c0f89a8 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/krb5-1.4.1-5.7.src.rpm b4a34b1b66194f86cd6163aa9a5879b4 Our maintenance customers are notified individually.

The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. 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) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> 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 SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security@suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: opensuse-security@opensuse.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security+subscribe@opensuse.org>. opensuse-security-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list.
