[security-announce] SUSE Security Announcement: bind remote denial of service (SUSE-SA:2011:029)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: bind Announcement ID: SUSE-SA:2011:029 Date: Fri, 08 Jul 2011 16:00:00 +0000 Affected Products: openSUSE 11.3 openSUSE 11.4 SUSE Linux Enterprise Software Development Kit 11 SP1 SUSE Linux Enterprise Desktop 11 SP1 SUSE Linux Enterprise Server 11 SP1 SUSE Linux Enterprise Desktop 10 SP4 SLE SDK 10 SP4 SUSE Linux Enterprise Server 10 SP4 Vulnerability Type: remote denial of service CVSS v2 Base Score: 7.8 (AV:N/AC:L/Au:N/C:N/I:N/A:C) SUSE Default Package: yes Cross-References: CVE-2011-2464, CVE-2011-2465 Content of This Advisory: 1) Security Vulnerability Resolved: bind remote denial of service issue Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: none 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion A remote Denial of Service vulnerability has been fixed in the BIND DNS nameserver. Specially crafted packets could cause bind servers (recursive as well as authoritative) to exit. (CVE-2011-2464) This issue affected bind 9.6 and later, so SUSE Linux Enterprise 10 SP4, SUSE Linux Enterprise 11 SP1 and openSUSE 11.3 and 11.4 were affected. Older service packs / products are not affected by CVE-2011-2464. Please also note that the other currently published security issue, CVE-2011-2465, affected only BIND versions 9.8.0 and later, which none of our current products include, making all of them not affected by this issue. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes The RPM update process should restart the named service automatically, but cross check if this happens and if it still correctly always as usual. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST "Online Update" module or the "zypper" commandline tool. The package and patch management stack will detect which updates are required and automatically perform 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 11.4: http://download.opensuse.org/update/11.4/rpm/i586/bind-9.7.3P3-0.2.1.i586.rp... http://download.opensuse.org/update/11.4/rpm/i586/bind-chrootenv-9.7.3P3-0.2... http://download.opensuse.org/update/11.4/rpm/i586/bind-devel-9.7.3P3-0.2.1.i... http://download.opensuse.org/update/11.4/rpm/i586/bind-libs-9.7.3P3-0.2.1.i5... http://download.opensuse.org/update/11.4/rpm/i586/bind-utils-9.7.3P3-0.2.1.i... openSUSE 11.3: http://download.opensuse.org/update/11.3/rpm/i586/bind-9.7.3P3-0.2.1.i586.rp... http://download.opensuse.org/update/11.3/rpm/i586/bind-chrootenv-9.7.3P3-0.2... http://download.opensuse.org/update/11.3/rpm/i586/bind-devel-9.7.3P3-0.2.1.i... http://download.opensuse.org/update/11.3/rpm/i586/bind-libs-9.7.3P3-0.2.1.i5... http://download.opensuse.org/update/11.3/rpm/i586/bind-utils-9.7.3P3-0.2.1.i...

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. 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. - 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-announce@opensuse.org - SUSE's announce-only mailing list.
