Affected Products:
openSUSE 11.2
______________________________________________________________________________

An update that fixes 38 vulnerabilities is now available.
It includes one version update.

Description:

This update of the openSUSE 11.2 kernel fixes lots of
security issues.

Following security issues were fixed: CVE-2011-1493: In the
rose networking stack, when parsing the FAC_NATIONAL_DIGIS
facilities field, it was possible for a remote host to
provide more digipeaters than expected, resulting in heap
corruption. Check against ROSE_MAX_DIGIS to prevent
overflows, and abort facilities parsing on failure.

CVE-2011-1182: Local attackers could send signals to their
programs that looked like coming from the kernel,
potentially gaining privileges in the context of setuid
programs.

CVE-2011-1082: The epoll subsystem in Linux did not prevent
users from creating circular epoll file structures,
potentially leading to a denial of service (kernel
deadlock).

CVE-2011-1163: The code for evaluating OSF partitions (in
fs/partitions/osf.c) contained a bug that leaks data from
kernel heap memory to userspace for certain corrupted OSF
partitions.

CVE-2011-1012: The code for evaluating LDM partitions (in
fs/partitions/ldm.c) contained a bug that could crash the
kernel for certain corrupted LDM partitions.

CVE-2011-1010: The code for evaluating Mac partitions (in
fs/partitions/mac.c) contained a bug that could crash the
kernel for certain corrupted Mac partitions.

CVE-2011-1476: Specially crafted requests may be written to
/dev/sequencer resulting in an underflow when calculating a
size for a copy_from_user() operation in the driver for
MIDI interfaces. On x86, this just returns an error, but it
could have caused memory corruption on other architectures.
Other malformed requests could have resulted in the use of
uninitialized variables.

CVE-2011-1477: Due to a failure to validate user-supplied
indexes in the driver for Yamaha YM3812 and OPL-3 chips, a
specially crafted ioctl request could have been sent to
/dev/sequencer, resulting in reading and writing beyond the
bounds of heap buffers, and potentially allowing privilege
escalation.

CVE-2011-1090: A page allocator issue in NFS v4 ACL
handling that could lead to a denial of service (crash) was
fixed.

CVE-2010-3880: net/ipv4/inet_diag.c in the Linux kernel did
not properly audit INET_DIAG bytecode, which allowed local
users to cause a denial of service (kernel infinite loop)
via crafted INET_DIAG_REQ_BYTECODE instructions in a
netlink message that contains multiple attribute elements,
as demonstrated by INET_DIAG_BC_JMP instructions.

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-2010-3705: The sctp_auth_asoc_get_hmac function in
net/sctp/auth.c in the Linux kernel did not properly
validate the hmac_ids array of an SCTP peer, which allowed
remote attackers to cause a denial of service (memory
corruption and panic) via a crafted value in the last
element of this array.

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

CVE-2011-0712: Multiple buffer overflows in the caiaq
Native Instruments USB audio functionality in the Linux
kernel might have allowed attackers to cause a denial of
service or possibly have unspecified other impact via a
long USB device name, related to (1) the
snd_usb_caiaq_audio_init function in
sound/usb/caiaq/audio.c and (2) the snd_usb_caiaq_midi_init
function in sound/usb/caiaq/midi.c.

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-2010-4248: 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
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-2010-4243: fs/exec.c in the Linux kernel did not enable
the OOM Killer to assess use of stack memory by arrays
representing the (1) arguments and (2) environment, which
allows local users to cause a denial of service (memory
consumption) via a crafted exec system call, aka an "OOM
dodging issue," a related issue to CVE-2010-3858.

CVE-2010-4648: Fixed cryptographic weakness potentially
leaking information to remote (but physically nearby) users
in the orinoco wireless driver.

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-2010-4668: 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-2010-4650: A kernel buffer overflow in the cuse server
module was fixed, which might have allowed local privilege
escalation. However only CUSE servers could exploit it and
/dev/cuse is normally restricted to root.

CVE-2010-4649: Integer overflow in the ib_uverbs_poll_cq
function in drivers/infiniband/core/uverbs_cmd.c in the
Linux kernel allowed local users to cause a denial of
service (memory corruption) or possibly have unspecified
other impact via a large value of a certain structure
member.

CVE-2010-4346: The install_special_mapping function in
mm/mmap.c in the Linux kernel did not make an expected
security_file_mmap function call, which allowed local users
to bypass intended mmap_min_addr restrictions and possibly
conduct NULL pointer dereference attacks via a crafted
assembly-language application.

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-2010-3849: The econet_sendmsg function in
net/econet/af_econet.c in the Linux kernel, when an econet
address is configured, allowed local users to cause a
denial of service (NULL pointer dereference and OOPS) via a
sendmsg call that specifies a NULL value for the remote
address field.

CVE-2010-3848: Stack-based buffer overflow in the
econet_sendmsg function in net/econet/af_econet.c in the
Linux kernel when an econet address is configured, allowed
local users to gain privileges by providing a large number
of iovec structures.

CVE-2010-3850: The ec_dev_ioctl function in
net/econet/af_econet.c in the Linux kernel did not require
the CAP_NET_ADMIN capability, which allowed local users to
bypass intended access restrictions and configure econet
addresses via an SIOCSIFADDR ioctl call.

CVE-2010-3699: The backend driver in Xen 3.x allows guest
OS users to cause a denial of service via a kernel thread
leak, which prevents the device and guest OS from being
shut down or create a zombie domain, causes a hang in
zenwatch, or prevents unspecified xm commands from working
properly, related to (1) netback, (2) blkback, or (3)
blktap.

CVE-2010-4073: The ipc subsystem in the Linux kernel did
not initialize certain structures, which allowed local
users to obtain potentially sensitive information from
kernel stack memory via vectors related to the (1)
compat_sys_semctl, (2) compat_sys_msgctl, and (3)
compat_sys_shmctl functions in ipc/compat.c; and the (4)
compat_sys_mq_open and (5) compat_sys_mq_getsetattr
functions in ipc/compat_mq.c.

CVE-2010-4072: The copy_shmid_to_user function in ipc/shm.c
in the Linux kernel did not initialize a certain structure,
which allowed local users to obtain potentially sensitive
information from kernel stack memory via vectors related to
the shmctl system call and the "old shm interface."

CVE-2010-4083: The copy_semid_to_user function in ipc/sem.c
in the Linux kernel did not initialize a certain structure,
which allowed local users to obtain potentially sensitive
information from kernel stack memory via a (1) IPC_INFO,
(2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT command in a
semctl system call.
