The Linux kernel on openSUSE 11.1 was updated to the stable version 2.6.27.19 and is also now at the same kernel as we are planning to ship with SUSE Linux Enterprise (Server/Desktop) 11. This update introduces kABI changes, so all kernel module packages also need to be rebuilt and reapplied. Rebuilt NVIDIA KMPs already are provided by NVIDIA, ATI and Madwifi KMPs will follow soon. Following security issues are fixed: CVE-2008-5079: net/atm/svc.c in the ATM subsystem in the Linux kernel allows local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table. CVE-2008-5700: libata in the Linux kernel does not set minimum timeouts for SG_IO requests, which allows local users to cause a denial of service (Programmed I/O mode on drives) via multiple simultaneous invocations of an unspecified test program. CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c in the Linux kernel might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call. CVE-2009-0028: A minor signal handling vulnerability was fixed, where a child could send his parent a arbitrary signal. CVE-2009-0029: The ABI in the Linux kernel on s390, PowerPC, sparc64, and MIPS 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call. CVE-2009-0031: Memory leak in the keyctl_join_session_keyring function (security/keys/keyctl.c) in Linux kernel allows local users to cause a denial of service (kernel memory consumption) via unknown vectors related to a "missing kfree." CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID. CVE-2009-0269:fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. CVE-2009-0322: drivers/firmware/dell_rbu.c in the Linux kernel allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/platform/dell_rbu/. 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 -Fhvto apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: openSUSE 11.1: https://download.opensuse.org/update/11.1/rpm/i586/kernel-debug-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-debug-base-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-debug-extra-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-default-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-default-base-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-default-extra-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-pae-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-pae-base-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-pae-extra-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-source-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-syms-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-trace-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-trace-base-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-trace-extra-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-vanilla-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-xen-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-xen-base-2.6.27.19-3.2.1.i586.rpm https://download.opensuse.org/update/11.1/rpm/i586/kernel-xen-extra-2.6.27.19-3.2.1.i586.rpm Platform Independent: openSUSE 11.1: https://download.opensuse.org/update/11.1/rpm/noarch/kernel-docs-2.6.3-3.13.5.noarch.rpm Power PC Platform: openSUSE 11.1: https://download.opensuse.org/update/11.1/rpm/ppc/kernel-default-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-default-base-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-default-extra-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-kdump-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-ppc64-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-ppc64-base-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-ppc64-extra-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-ps3-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-source-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-syms-2.6.27.19-3.2.1.ppc.rpm https://download.opensuse.org/update/11.1/rpm/ppc/kernel-vanilla-2.6.27.19-3.2.1.ppc.rpm x86-64 Platform: openSUSE 11.1: https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-debug-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-debug-base-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-debug-extra-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-default-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-default-base-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-default-extra-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-source-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-syms-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-trace-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-trace-base-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-trace-extra-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-vanilla-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-xen-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-xen-base-2.6.27.19-3.2.1.x86_64.rpm https://download.opensuse.org/update/11.1/rpm/x86_64/kernel-xen-extra-2.6.27.19-3.2.1.x86_64.rpm Sources: openSUSE 11.1: ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. ______________________________________________________________________________ 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 replacing with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team " where 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.
