Following security issues were fixed: CVE-2010-4655: A memory leak in the ethtool ioctl was fixed that could disclose kernel memory to local attackers with CAP_NET_ADMIN privileges. CVE-2011-0521: The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel did not check the sign of a certain integer field, which allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value. CVE-2010-3875: The ax25_getname function in net/ax25/af_ax25.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure. CVE-2010-3876: net/packet/af_packet.c in the Linux kernel did not properly initialize certain structure members, which allowed local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_RAW capability to read copies of the applicable structures. CVE-2010-3877: The get_name function in net/tipc/socket.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure. CVE-2011-0711: A stack memory information leak in the xfs FSGEOMETRY_V1 ioctl was fixed. CVE-2011-0710: The task_show_regs function in arch/s390/kernel/traps.c in the Linux kernel on the s390 platform allowed local users to obtain the values of the registers of an arbitrary process by reading a status file under /proc/. CVE-2010-1173: The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel, when SCTP is enabled, allowed remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. CVE-2010-4075: The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call. CVE-2010-4076: The rs_ioctl function in drivers/char/amiserial.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call. CVE-2010-4077: The ntty_ioctl_tiocgicount function in drivers/char/nozomi.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call. CVE-2010-4527: The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel incorrectly expected that a certain name field ends with a '0' character, which allowed local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call. CVE-2010-4248: Race condition in the __exit_signal function in kernel/exit.c in the Linux kernel allowed local users to cause a denial of service via vectors related to multi threaded exec, the use of a thread group leader in kernel/posix-cpu-timers.c, and the selection of a new thread group leader in the de_thread function in fs/exec.c. CVE-2010-4668: The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel allowed local users to cause a denial of service (panic) via a zero-length I/O request in a device ioctl to a SCSI device, related to an unaligned map. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4163. CVE-2010-4242: The hci_uart_tty_open function in the HCI UART driver (drivers/bluetooth/hci_ldisc.c) in the Linux kernel did not verify whether the tty has a write operation, which allowed local users to cause a denial of service (NULL pointer dereference) via vectors related to the Bluetooth driver. CVE-2010-4529: Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel on platforms other than x86 allowed local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call. CVE-2010-4342: The aun_incoming function in net/econet/af_econet.c in the Linux kernel, when Econet is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending an Acorn Universal Networking (AUN) packet over UDP. CVE-2010-4526: Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel allowed remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function. 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" module or the "zypper" commandline tool. The package and patch management stack will detect which updates are required and automatically perform 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: SUSE Linux Enterprise Desktop 10 SP3 for AMD64 and Intel EM64T http://download.novell.com/patch/finder/?keywords=2119b714456dc8c3d29661b68c...

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.
