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 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-bigsmp... 1a12e1aacec911f5c08279f5ef98847f http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-debug-... 4a53ab56b281fd86dd0d206d512731f7 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-defaul... 960032b6e3c89616bb12e2e92cb8aef6 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-source... 390ad049b12300321fe35bcdb88b7c31 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-syms-2... 3056141e73f37a521c52bb55fcd76006 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-xen-2.... 89d63df290a8f2e2dc7ceb85f77d6533 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/kernel-xenpae... 443f87738be5368e7bb28936157c6c01 Power PC Platform: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/kernel-default... b776981525527e92dc461b20cd54a4e5 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/kernel-kdump-2... 35391438b5df1eb49874929b41063b89 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/kernel-ppc64-2... 3052960e883737aa3c29a9633e1e0ea8 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/kernel-source-... e1aaee8d102ab448f1e2111b7c3bcb87 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/kernel-syms-2.... f3a79e7be26c2ed4f4112cee14bb7a78 x86-64 Platform: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/kernel-debu... 867bdea7dfd4a643a424e46b82bbe912 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/kernel-defa... 0df6d8269e9b2674c34fb609942fbf32 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/kernel-sour... 5cfd1c3745f1d7ad329eb94393df990e http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/kernel-syms... 5c368bbe01e6667f8234677a010d5764 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/kernel-xen-... b5b3b7cb20914407296ec87e8437cf20 Sources: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-bigsmp-... b6c70308122a82a656574d4198437ee0 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-debug-2... f1bd6bd6399346959919679c15766bdd http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-default... 7fb25a4f00225b2430eb41221e09bacc http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-kdump-2... f1941735af850af06c542469c6b16a3d http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-ppc64-2... f89babffcbfc64cc8efbe16283ddfdca http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-source-... a1c6fa14f08682419b8f4f5fc5e0b8a4 http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-syms-2.... 75c585e0a4276542dd6828080aa7f29c http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-xen-2.6... cf5c174deb9b4588e3b7708236d9cb8c http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/kernel-xenpae-... b7685baa4f3cabcbe5c9291edfde1c39 ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: none ______________________________________________________________________________ 6) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. 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.
