-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2008:044 Date: Thu, 11 Sep 2008 11:00:00 +0000 Affected Products: openSUSE 11.0 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2008-1673, CVE-2008-3272, CVE-2008-3275 CVE-2008-3276 Content of This Advisory: 1) Security Vulnerability Resolved: kernel security update Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion The openSUSE 11.0 kernel was updated to 2.6.25.16. It fixes various stability bugs and also security bugs. CVE-2008-1673: Fixed the range checking in the ASN.1 decoder in NAT for SNMP and CIFS, which could have been used by a remote attacker to crash the machine. CVE-2008-3276: An integer overflow flaw was found in the Linux kernel dccp_setsockopt_change() function. An attacker may leverage this vulnerability to trigger a kernel panic on a victim's machine remotely. CVE-2008-3272: The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem does not verify that the device number is within the range defined by max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive information. CVE-2008-3275: The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories. Also lots of bugs were fixed. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please restart your machine after installing the update. 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 11.0: http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/debug/update/11.0/rpm/i586/kernel-... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-debug-... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-defaul... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-pae-2.... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-rt-2.6... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-rt_deb... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-source... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-syms-2... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-vanill... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/kernel-xen-2....

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.
