SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 7381)

This script is Copyright (C) 2011-2016 Tenable Network Security, Inc.


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)
