This problem could be used by remote authenticated attackers that have access to the samba daemon. Two other problems fixed in the upstream samba security release that do not affect the SUSE Samba version: - CVE-2007-0454: A format string problem in AFS ACL handling. None of our shipping Samba versions have this option compiled in. - CVE-2007-0453: A buffer overflow in nss_winbind on Solaris. Linux is generally not affected by this problem. 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 to apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/samba-3.0.23d-19.2.i586.rpm 6b4cb2859d1321648fd46c30a6cfd343 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/samba-client-3.0.23d-19.2.i586.rpm b168ff8f07a792bf6fb66a91c893ae33 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/samba-winbind-3.0.23d-19.2.i586.rpm 23e180e09af077fd64b35d8154d414c6 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/samba-3.0.22-13.27.i586.rpm 898c1eb0d0d4f1c806ce7fb8907753d7 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/samba-client-3.0.22-13.27.i586.rpm d4f4efa7488aa12edd8f9ac2074fbbc3 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/samba-winbind-3.0.22-13.27.i586.rpm f2d11fdea4fa460cfb5bda4e20fc5e86 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/samba-3.0.20b-3.8.i586.rpm ce7bcec67ee32a5415d4cb5907ec0372 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/samba-3.0.13-1.6.i586.rpm 7cc438d1cc0e8d4f479844bfccc8f698 Power PC Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/samba-3.0.23d-19.2.ppc.rpm d3b20aff8d493b48741b160c223bd268 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/samba-client-3.0.23d-19.2.ppc.rpm 790670189510dce128dca2f3f32f2b9c ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/samba-winbind-3.0.23d-19.2.ppc.rpm 43815e4efd08eae9e26242be281ba2fe SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/samba-3.0.22-13.27.ppc.rpm a2d2ce421081a74258c5328a5a432629 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/samba-client-3.0.22-13.27.ppc.rpm f86d3c623aadc34f1f64f173108f9c4b ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/samba-winbind-3.0.22-13.27.ppc.rpm b95e5643763b4f172adec030fa9033be SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/samba-3.0.20b-3.8.ppc.rpm 8badc1520efe79ac17b053be83648e46 x86-64 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-3.0.23d-19.2.x86_64.rpm a23ee65e112c499b91af6c00ab068efa ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-32bit-3.0.23d-19.2.x86_64.rpm 09785d54c57f6da705acfa0f911b0b8d ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-client-3.0.23d-19.2.x86_64.rpm c4b7be8c144842fd6947bfa7bf56891a ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-client-32bit-3.0.23d-19.2.x86_64.rpm 5a474e36e2f20b086138fb1d7a225942 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-winbind-3.0.23d-19.2.x86_64.rpm c3ebad542ec53b71d3641310f796b430 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/samba-winbind-32bit-3.0.23d-19.2.x86_64.rpm 1d0480ab089c3be84de54bc6bad71910 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-3.0.22-13.27.x86_64.rpm be6125ae205f2274150a29a4c251e8c0 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-32bit-3.0.22-13.27.x86_64.rpm 6bd817cbdf52fd2e4ff8257442ba1d60 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-client-3.0.22-13.27.x86_64.rpm 5cd72ad1de6b29173a9e3d23a1012b2c ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-client-32bit-3.0.22-13.27.x86_64.rpm a6509bd2aa7b9c7421e4d1777ce2bba3 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-winbind-3.0.22-13.27.x86_64.rpm 0d3cb4f0c3bcef1a5569dd5d72b3c73b ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/samba-winbind-32bit-3.0.22-13.27.x86_64.rpm e9dbf740b218735e385a348524d31108 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/samba-3.0.20b-3.8.x86_64.rpm f0ad5468ce42ff2631e9a6b3231010c1 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/samba-3.0.13-1.6.x86_64.rpm fbd0c2a208fd91da991e53b54fb1a57d Sources: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/src/samba-3.0.23d-19.2.src.rpm 54d62f5dad95981f0ae894619d0f06ea SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/samba-3.0.22-13.27.src.rpm 8b2e1c4b662fc43fa03fe1ba60342c00 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/samba-3.0.20b-3.8.src.rpm 9217074c11c43c30860be28b33f034dd SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/samba-3.0.13-1.6.src.rpm 117006e9e50e888e4848aa320e88b18d 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 " 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 to verify the signature of the package, replacing 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 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 . suse-security-announce@suse.com - SUSE's announce-only mailing list.
