This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

The SUSE Linux Enterprise Server 11 SP1 LTSS received a roll up update
to fix several security and non-security issues.

The following security issues have been fixed :

- CVE-2013-1860: Heap-based buffer overflow in the
wdm_in_callback function in drivers/usb/class/cdc-wdm.c
in the Linux kernel before 3.8.4 allows physically
proximate attackers to cause a denial of service (system
crash) or possibly execute arbitrary code via a crafted
cdc-wdm USB device. (bnc#806431)

- CVE-2013-4162: The udp_v6_push_pending_frames function
in net/ipv6/udp.c in the IPv6 implementation in the
Linux kernel through 3.10.3 makes an incorrect function
call for pending data, which allows local users to cause
a denial of service (BUG and system crash) via a crafted
application that uses the UDP_CORK option in a
setsockopt system call. (bnc#831058)

- CVE-2014-0203: The __do_follow_link function in
fs/namei.c in the Linux kernel before 2.6.33 does not
properly handle the last pathname component during use
of certain filesystems, which allows local users to
cause a denial of service (incorrect free operations and
system crash) via an open system call. (bnc#883526)

- CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)
BPF_S_ANC_NLATTR_NEST extension implementations in the
sk_run_filter function in net/core/filter.c in the Linux
kernel through 3.14.3 do not check whether a certain
length value is sufficiently large, which allows local
users to cause a denial of service (integer underflow
and system crash) via crafted BPF instructions. NOTE:
the affected code was moved to the __skb_get_nlattr and
__skb_get_nlattr_nest functions before the vulnerability
was announced. (bnc#877257)

- CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension
implementation in the sk_run_filter function in
net/core/filter.c in the Linux kernel through 3.14.3
uses the reverse order in a certain subtraction, which
allows local users to cause a denial of service
(over-read and system crash) via crafted BPF
instructions. NOTE: the affected code was moved to the
__skb_get_nlattr_nest function before the vulnerability
was announced. (bnc#877257)

- CVE-2014-3917: kernel/auditsc.c in the Linux kernel
through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with
certain syscall rules, allows local users to obtain
potentially sensitive single-bit values from kernel
memory or cause a denial of service (OOPS) via a large
value of a syscall number. (bnc#880484)

- CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux
kernel through 3.15.1 on 32-bit x86 platforms, when
syscall auditing is enabled and the sep CPU feature flag
is set, allows local users to cause a denial of service
(OOPS and system crash) via an invalid syscall number,
as demonstrated by number 1000. (bnc#883724)

- CVE-2014-4652: Race condition in the tlv handler
functionality in the snd_ctl_elem_user_tlv function in
sound/core/control.c in the ALSA control implementation
in the Linux kernel before 3.15.2 allows local users to
obtain sensitive information from kernel memory by
leveraging /dev/snd/controlCX access. (bnc#883795)

- CVE-2014-4653: sound/core/control.c in the ALSA control
implementation in the Linux kernel before 3.15.2 does
not ensure possession of a read/write lock, which allows
local users to cause a denial of service
(use-after-free) and obtain sensitive information from
kernel memory by leveraging /dev/snd/controlCX access.
(bnc#883795)

- CVE-2014-4654: The snd_ctl_elem_add function in
sound/core/control.c in the ALSA control implementation
in the Linux kernel before 3.15.2 does not check
authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands,
which allows local users to remove kernel controls and
cause a denial of service (use-after-free and system
crash) by leveraging /dev/snd/controlCX access for an
ioctl call. (bnc#883795)

- CVE-2014-4655: The snd_ctl_elem_add function in
sound/core/control.c in the ALSA control implementation
in the Linux kernel before 3.15.2 does not properly
maintain the user_ctl_count value, which allows local
users to cause a denial of service (integer overflow and
limit bypass) by leveraging /dev/snd/controlCX access
for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl
calls. (bnc#883795)

- CVE-2014-4656: Multiple integer overflows in
sound/core/control.c in the ALSA control implementation
in the Linux kernel before 3.15.2 allow local users to
cause a denial of service by leveraging
/dev/snd/controlCX access, related to (1) index values
in the snd_ctl_add function and (2) numid values in the
snd_ctl_remove_numid_conflict function. (bnc#883795)

- CVE-2014-4667: The sctp_association_free function in
net/sctp/associola.c in the Linux kernel before 3.15.2
does not properly manage a certain backlog value, which
allows remote attackers to cause a denial of service
(socket outage) via a crafted SCTP packet. (bnc#885422)

- CVE-2014-4699: The Linux kernel before 3.15.4 on Intel
processors does not properly restrict use of a
non-canonical value for the saved RIP address in the
case of a system call that does not use IRET, which
allows local users to leverage a race condition and gain
privileges, or cause a denial of service (double fault),
via a crafted application that makes ptrace and fork
system calls. (bnc#885725)

- CVE-2014-4943: The PPPoL2TP feature in
net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6
allows local users to gain privileges by leveraging
data-structure differences between an l2tp socket and an
inet socket. (bnc#887082)

- CVE-2014-5077: The sctp_assoc_update function in
net/sctp/associola.c in the Linux kernel through 3.15.8,
when SCTP authentication is enabled, allows remote
attackers to cause a denial of service (NULL pointer
dereference and OOPS) by starting to establish an
association between two endpoints immediately after an
exchange of INIT and INIT ACK chunks to establish an
earlier association between these endpoints in the
opposite direction. (bnc#889173)

- CVE-2013-7266: The mISDN_sock_recvmsg function in
drivers/isdn/mISDN/socket.c in the Linux kernel before
3.12.4 does not ensure that a certain length value is
consistent with the size of an associated data
structure, which allows local users to obtain sensitive
information from kernel memory via a (1) recvfrom, (2)
recvmmsg, or (3) recvmsg system call. (bnc#854722)

- CVE-2013-7267: The atalk_recvmsg function in
net/appletalk/ddp.c in the Linux kernel before 3.12.4
updates a certain length value without ensuring that an
associated data structure has been initialized, which
allows local users to obtain sensitive information from
kernel memory via a (1) recvfrom, (2) recvmmsg, or (3)
recvmsg system call. (bnc#854722)

- CVE-2013-7268: The ipx_recvmsg function in
net/ipx/af_ipx.c in the Linux kernel before 3.12.4
updates a certain length value without ensuring that an
associated data structure has been initialized, which
allows local users to obtain sensitive information from
kernel memory via a (1) recvfrom, (2) recvmmsg, or (3)
recvmsg system call. (bnc#854722)

- CVE-2013-7269: The nr_recvmsg function in
net/netrom/af_netrom.c in the Linux kernel before 3.12.4
updates a certain length value without ensuring that an
associated data structure has been initialized, which
allows local users to obtain sensitive information from
kernel memory via a (1) recvfrom, (2) recvmmsg, or (3)
recvmsg system call. (bnc#854722)

- CVE-2013-7270: The packet_recvmsg function in
net/packet/af_packet.c in the Linux kernel before 3.12.4
updates a certain length value before ensuring that an
associated data structure has been initialized, which
allows local users to obtain sensitive information from
kernel memory via a (1) recvfrom, (2) recvmmsg, or (3)
recvmsg system call. (bnc#854722)

- CVE-2013-7271: The x25_recvmsg function in
net/x25/af_x25.c in the Linux kernel before 3.12.4
updates a certain length value without ensuring that an
associated data structure has been initialized, which
allows local users to obtain sensitive information from
kernel memory via a (1) recvfrom, (2) recvmmsg, or (3)
recvmsg system call. (bnc#854722)

The following bugs have been fixed :

- mac80211: Fix AP powersave TX vs. wakeup race
(bnc#871797).
