openSUSE Security Update : kernel (openSUSE-SU-2011:0004-1)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

The openSUSE 11.3 kernel was updated to fix various bugs and security
issues.

Following security issues have been fixed: CVE-2010-4347: A local user
could inject ACPI code into the kernel via the world-writable
'custom_debug' file, allowing local privilege escalation.

CVE-2010-4258: A local attacker could use a Oops (kernel crash) caused
by other flaws to write a 0 byte to a attacker controlled address in
the kernel. This could lead to privilege escalation together with
other issues.

CVE-2010-4157: A 32bit vs 64bit integer mismatch in gdth_ioctl_alloc
could lead to memory corruption in the GDTH driver.

CVE-2010-4165: The do_tcp_setsockopt function in net/ipv4/tcp.c in the
Linux kernel did not properly restrict TCP_MAXSEG (aka MSS) values,
which allows local users to cause a denial of service (OOPS) via a
setsockopt call that specifies a small value, leading to a
divide-by-zero error or incorrect use of a signed integer.

CVE-2010-4164: A remote (or local) attacker communicating over X.25
could cause a kernel panic by attempting to negotiate malformed
facilities.

CVE-2010-4175: A local attacker could cause memory overruns in the RDS
protocol stack, potentially crashing the kernel. So far it is
considered not to be exploitable.

CVE-2010-4169: Use-after-free vulnerability in mm/mprotect.c in the
Linux kernel allwed local users to cause a denial of service via
vectors involving an mprotect system call.

CVE-2010-3874: A minor heap overflow in the CAN network module was
fixed. Due to nature of the memory allocator it is likely not
exploitable.

CVE-2010-4158: A memory information leak in berkely packet filter
rules allowed local attackers to read uninitialized memory of the
kernel stack.

CVE-2010-4162: A local denial of service in the blockdevice layer was
fixed.

CVE-2010-4163: By submitting certain I/O requests with 0 length, a
local user could have caused a kernel panic.

CVE-2010-0435: The Hypervisor in KVM 83, when the Intel VT-x extension
is enabled, allows guest OS users to cause a denial of service (NULL
pointer dereference and host OS crash) via vectors related to
instruction emulation.

CVE-2010-3861: The ethtool_get_rxnfc function in net/core/ethtool.c in
the Linux kernel did not initialize a certain block of heap memory,
which allowed local users to obtain potentially sensitive information
via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt
value.

CVE-2010-3442: Multiple integer overflows in the snd_ctl_new function
in sound/core/control.c in the Linux kernel allowed local users to
cause a denial of service (heap memory corruption) or possibly have
unspecified other impact via a crafted (1) SNDRV_CTL_IOCTL_ELEM_ADD or
(2) SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl call.

CVE-2010-3437: A range checking overflow in pktcdvd ioctl was fixed.

CVE-2010-4078: The sisfb_ioctl function in
drivers/video/sis/sis_main.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
an FBIOGET_VBLANK ioctl call.

CVE-2010-4080: The snd_hdsp_hwdep_ioctl function in
sound/pci/rme9652/hdsp.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 an
SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl call.

CVE-2010-4081: The snd_hdspm_hwdep_ioctl function in
sound/pci/rme9652/hdspm.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 an
SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.

CVE-2010-4082: The viafb_ioctl_get_viafb_info function in
drivers/video/via/ioctl.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 VIAFB_GET_INFO ioctl call.

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.

CVE-2010-3432: The sctp_packet_config function in net/sctp/output.c in
the Linux kernel performed extraneous initializations of packet data
structures, which allowed remote attackers to cause a denial of
service (panic) via a certain sequence of SCTP traffic.

CVE-2010-3067: Integer overflow in the do_io_submit function in
fs/aio.c in the Linux kernel allowed local users to cause a denial of
service or possibly have unspecified other impact via crafted use of
the io_submit system call.

CVE-2010-3865: A iovec integer overflow in RDS sockets was fixed which
could lead to local attackers gaining kernel privileges.
