Synopsis

The remote SuSE 10 host is missing a security-related patch.

Description

This kernel update for the SUSE Linux Enterprise 10 SP3 kernel fixes several security issues and bugs.

The following security issues were fixed :

- A memory leak in the ethtool ioctl was fixed that could disclose kernel memory to local attackers with CAP_NET_ADMIN privileges. (CVE-2010-4655)

- 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-2011-0521)

- 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-2010-3875)

- 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-2010-3876)

- 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-2010-3877)

- A stack memory information leak in the xfs FSGEOMETRY_V1 ioctl was fixed. (CVE-2011-0711)

- 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-2011-0710)

- 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-2010-1173)

- 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-2010-4075)

- 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-2010-4076)

- 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-2010-4077)

- 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-2010-4527)

- 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 multithreaded 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-2010-4248)

- 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-2010-4668)

- 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-2010-4242)

- 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-2010-4529)

- 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-2010-4342)

- 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. (CVE-2010-4526)

Solution

Apply ZYPP patch number 7381.
