-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2010:047 5ate: Thu, 23 Sep 2010 16:00:00 +0000 Affected Products: openSUSE 11.3 Vulnerability Type: local privilege escalation CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C) SUSE Default Package: yes Cross-References: CVE-2010-2955, CVE-2010-2959, CVE-2010-2960 CVE-2010-3079, CVE-2010-3080, CVE-2010-3081 CVE-2010-3084, CVE-2010-3296, CVE-2010-3297 CVE-2010-3298, CVE-2010-3301 Content of This Advisory: 1) Security Vulnerability Resolved: Linux 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 This update of the openSUSE 11.3 kernel fixes two local root exploits, various other security issues and some bugs. Following security issues are fixed by this update: CVE-2010-3301: Mismatch between 32bit and 64bit register usage in the system call entry path could be used by local attackers to gain root privileges. This problem only affects x86_64 kernels. CVE-2010-3081: Incorrect buffer handling in the biarch-compat buffer handling could be used by local attackers to gain root privileges. This problem affects foremost x86_64, or potentially other biarch platforms, like PowerPC and S390x. CVE-2010-3084: A buffer overflow in the ETHTOOL_GRXCLSRLALL code could be used to crash the kernel or potentially execute code. CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed. CVE-2010-2960: The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function. CVE-2010-3080: A double free in an alsa error path was fixed, which could lead to kernel crashes. CVE-2010-3079: Fixed a ftrace NULL pointer dereference problem which could lead to kernel crashes. CVE-2010-3298: Fixed a kernel information leak in the net/usb/hso driver. CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver. CVE-2010-3297: Fixed a kernel information leak in the net/eql driver. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please reboot the 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 11.3: http://download.opensuse.org/update/11.3/rpm/i586/kernel-debug-2.6.34.7-0.3.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-debug-base-2.6.34.7... http://download.opensuse.org/update/11.3/rpm/i586/kernel-debug-devel-2.6.34.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-default-2.6.34.7-0.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-default-base-2.6.34... http://download.opensuse.org/update/11.3/rpm/i586/kernel-default-devel-2.6.3... http://download.opensuse.org/update/11.3/rpm/i586/kernel-desktop-2.6.34.7-0.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-desktop-base-2.6.34... http://download.opensuse.org/update/11.3/rpm/i586/kernel-desktop-devel-2.6.3... http://download.opensuse.org/update/11.3/rpm/i586/kernel-ec2-2.6.34.7-0.3.1.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-ec2-base-2.6.34.7-0... http://download.opensuse.org/update/11.3/rpm/i586/kernel-ec2-devel-2.6.34.7-... http://download.opensuse.org/update/11.3/rpm/i586/kernel-ec2-extra-2.6.34.7-... http://download.opensuse.org/update/11.3/rpm/i586/kernel-pae-2.6.34.7-0.3.1.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-pae-base-2.6.34.7-0... http://download.opensuse.org/update/11.3/rpm/i586/kernel-pae-devel-2.6.34.7-... http://download.opensuse.org/update/11.3/rpm/i586/kernel-syms-2.6.34.7-0.3.1... http://download.opensuse.org/update/11.3/rpm/i586/kernel-trace-2.6.34.7-0.3.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-trace-base-2.6.34.7... http://download.opensuse.org/update/11.3/rpm/i586/kernel-trace-devel-2.6.34.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vanilla-2.6.34.7-0.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vanilla-base-2.6.34... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vanilla-devel-2.6.3... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vmi-2.6.34.7-0.3.1.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vmi-base-2.6.34.7-0... http://download.opensuse.org/update/11.3/rpm/i586/kernel-vmi-devel-2.6.34.7-... http://download.opensuse.org/update/11.3/rpm/i586/kernel-xen-2.6.34.7-0.3.1.... http://download.opensuse.org/update/11.3/rpm/i586/kernel-xen-base-2.6.34.7-0... http://download.opensuse.org/update/11.3/rpm/i586/kernel-xen-devel-2.6.34.7-... http://download.opensuse.org/update/11.3/rpm/i586/preload-kmp-default-1.1_k2... http://download.opensuse.org/update/11.3/rpm/i586/preload-kmp-desktop-1.1_k2...

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.
