-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2009:015 Date: Fri, 03 Apr 2009 11:00:00 +0000 Affected Products: SUSE SLES 9 Novell Linux Desktop 9 Open Enterprise Server Novell Linux POS 9 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2009-0028, CVE-2009-0065, CVE-2009-0322 CVE-2009-0675, CVE-2009-0676 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 The SUSE Linux Enterprise 9 kernel has been updated to fix lots of bugs and several security issues. Following security issues were fixed: CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit. CVE-2009-0675: The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an "inverted logic" issue. CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. 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/. 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. The update was already released last Friday. 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 <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web: Novell Linux Desktop 9 for x86 http://download.novell.com/index.jsp?search=Search&keywords=c7655805ae75e4234d9dc24b9dccb316 Open Enterprise Server http://download.novell.com/index.jsp?search=Search&keywords=c7655805ae75e4234d9dc24b9dccb316 http://download.novell.com/index.jsp?search=Search&keywords=c7c9b16e331ce5bf253ab2a28b5bd77d Novell Linux POS 9 http://download.novell.com/index.jsp?search=Search&keywords=673db0fba9a8a4f380391d496876b759 http://download.novell.com/index.jsp?search=Search&keywords=c7c9b16e331ce5bf253ab2a28b5bd77d SUSE CORE 9 for x86 http://download.novell.com/index.jsp?search=Search&keywords=673db0fba9a8a4f380391d496876b759 http://download.novell.com/index.jsp?search=Search&keywords=c7c9b16e331ce5bf253ab2a28b5bd77d SUSE CORE 9 for AMD64 and Intel EM64T http://download.novell.com/index.jsp?search=Search&keywords=eecc8d276b42eb926842d2839ea9afaf SUSE CORE 9 for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&keywords=3b700931e4ae8f2a03b1649edd2eda56 SUSE CORE 9 for IBM S/390 31bit http://download.novell.com/index.jsp?search=Search&keywords=5734912fdd1d59cddd357f791707416a SUSE CORE 9 for IBM POWER http://download.novell.com/index.jsp?search=Search&keywords=b33c1669e547b2fb729dba29d5d0c433 SUSE SLES 9 http://download.novell.com/index.jsp?search=Search&keywords=673db0fba9a8a4f380391d496876b759 http://download.novell.com/index.jsp?search=Search&keywords=eecc8d276b42eb926842d2839ea9afaf http://download.novell.com/index.jsp?search=Search&keywords=3b700931e4ae8f2a03b1649edd2eda56 http://download.novell.com/index.jsp?search=Search&keywords=5734912fdd1d59cddd357f791707416a http://download.novell.com/index.jsp?search=Search&keywords=b33c1669e547b2fb729dba29d5d0c433 http://download.novell.com/index.jsp?search=Search&keywords=e29bce0eee4524e4bb8dfcf6de2c6699 SUSE CORE 9 for Itanium Processor Family http://download.novell.com/index.jsp?search=Search&keywords=e29bce0eee4524e4bb8dfcf6de2c6699 Novell Linux Desktop 9 http://download.novell.com/index.jsp?search=Search&keywords=c7655805ae75e4234d9dc24b9dccb316 http://download.novell.com/index.jsp?search=Search&keywords=a5f830cc07634abf9262d8a651634e2b Novell Linux Desktop 9 for x86_64 http://download.novell.com/index.jsp?search=Search&keywords=a5f830cc07634abf9262d8a651634e2b ______________________________________________________________________________ 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 <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. 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. - 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. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security-announce+subscribe@opensuse.org>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>. The <security@suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way. In particular, the clear text signature should show proof of the authenticity of the text.
