CVE-2009-4005: The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read. CVE-2009-3080: Array index error in the gdth_read_event function in drivers/scsi/gdth.c in the Linux kernel allows local users to cause a denial of service or possibly gain privileges via a negative event index in an IOCTL request. CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. CVE-2009-3889: The dbg_lvl file for the megaraid_sas driver in the Linux kernel has world-writable permissions, which allows local users to change the (1) behavior and (2) logging level of the driver by modifying this file. CVE-2009-1883: The z90crypt_unlocked_ioctl function in the z90crypt driver in the Linux kernel does not perform a capability check for the Z90QUIESCE operation, which allows local users to leverage euid 0 privileges to force a driver outage. CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel, when the appletalk and ipddp modules are loaded but the ipddp"N" device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. 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. Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web: SUSE CORE 9 for Itanium Processor Family http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=f244ff5c3b3396176b5103f1715e6684 SUSE CORE 9 for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=a31f023a60d07c8888e454fa1d125def SUSE CORE 9 for IBM S/390 31bit http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=687ae9e3794e96759e414f98fbdce2b2 SUSE CORE 9 for AMD64 and Intel EM64T http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=4267d3a69718225e2fb2c25170bc6d94 Novell Linux POS 9 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=115c23c0f70fab25bce4f2dedb036c6c SUSE CORE 9 for x86 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=115c23c0f70fab25bce4f2dedb036c6c SUSE SLES 9 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=f244ff5c3b3396176b5103f1715e6684 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=a31f023a60d07c8888e454fa1d125def http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=687ae9e3794e96759e414f98fbdce2b2 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=4267d3a69718225e2fb2c25170bc6d94 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=115c23c0f70fab25bce4f2dedb036c6c http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=07c0f8cc874baafd99ac348e3dc688c7 SUSE CORE 9 for IBM POWER http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=07c0f8cc874baafd99ac348e3dc688c7 ______________________________________________________________________________ 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 " 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.
