Summary

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

The following security bugs were fixed :

  - CVE-2016-7117: Use-after-free vulnerability in the
    __sys_recvmmsg function in net/socket.c in the Linux
    kernel allowed remote attackers to execute arbitrary
    code via vectors involving a recvmmsg system call that
    is mishandled during error processing (bnc#1003077
    1003253).

  - CVE-2017-5576, CVE-2017-5577: A buffer overflow in the
    VC4_SUBMIT_CL IOCTL in the VideoCore DRM driver for
    Raspberry Pi was fixed. (bsc#1021294)

  - CVE-2017-5551: tmpfs: Fixed a bug that could have
    allowed users to set setgid bits on files they don't
    down. (bsc#1021258).

  - CVE-2017-2583: A Linux kernel built with the
    Kernel-based Virtual Machine (CONFIG_KVM) support was
    vulnerable to an incorrect segment selector(SS) value
    error. A user/process inside guest could have used this
    flaw to crash the guest resulting in DoS or potentially
    escalate their privileges inside guest. (bsc#1020602).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux
    kernel allowed local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (use-after-free) via a crafted application that
    leverages instruction emulation for fxrstor, fxsave,
    sgdt, and sidt (bnc#1019851).

  - CVE-2015-8709: ** DISPUTED ** kernel/ptrace.c in the
    Linux kernel mishandled uid and gid mappings, which
    allowed local users to gain privileges by establishing a
    user namespace, waiting for a root process to enter that
    namespace with an unsafe uid or gid, and then using the
    ptrace system call. NOTE: the vendor states 'there is no
    kernel bug here (bnc#959709 bsc#960561).

  - CVE-2016-9806: Race condition in the netlink_dump
    function in net/netlink/af_netlink.c in the Linux kernel
    allowed local users to cause a denial of service (double
    free) or possibly have unspecified other impact via a
    crafted application that made sendmsg system calls,
    leading to a free operation associated with a new dump
    that started earlier than anticipated (bnc#1013540
    1017589).

  - CVE-2016-8645: The TCP stack in the Linux kernel
    mishandled skb truncation, which allowed local users to
    cause a denial of service (system crash) via a crafted
    application that made sendto system calls, related to
    net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
    (bnc#1009969).

  - CVE-2016-9793: The sock_setsockopt function in
    net/core/sock.c in the Linux kernel mishandled negative
    values of sk_sndbuf and sk_rcvbuf, which allowed local
    users to cause a denial of service (memory corruption
    and system crash) or possibly have unspecified other
    impact by leveraging the CAP_NET_ADMIN capability for a
    crafted setsockopt system call with the (1)
    SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531
    bsc#1013542).

  - CVE-2016-9919: The icmp6_send function in
    net/ipv6/icmp.c in the Linux kernel omits a certain

    descriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.38 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7039: The IP stack in the Linux kernel allowed remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666 (bnc#1001486). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message

"The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.38 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x
    provides an incomplete set of requirements for setattr
    operations that underspecifies removing extended
    privilege attributes, which allowed local users to cause
    a denial of service (capability stripping) via a failed
    invocation of a system call, as demonstrated by using
    chown to remove a capability from the ping or Wireshark
    dumpcap program (bnc#914939).

  - CVE-2015-8964: The tty_set_termios_ldisc function in
    drivers/tty/tty_ldisc.c in the Linux kernel allowed
    local users to obtain sensitive information from kernel
    memory by reading a tty data structure (bnc#1010507).

  - CVE-2016-7039: The IP stack in the Linux kernel allowed
    remote attackers to cause a denial of service (stack
    consumption and panic) or possibly have unspecified
    other impact by triggering use of the GRO path for large
    crafted packets, as demonstrated by packets that contain
    only VLAN headers, a related issue to CVE-2016-8666
    (bnc#1001486).

  - CVE-2016-7042: The proc_keys_show function in
    security/keys/proc.c in the Linux kernel through 4.8.2,
    when the GNU Compiler Collection (gcc) stack protector
    is enabled, uses an incorrect buffer size for certain
    timeout data, which allowed local users to cause a
    denial of service (stack memory corruption and panic) by
    reading the /proc/keys file (bnc#1004517).

  - CVE-2016-7425: The arcmsr_iop_message_xfer function in
    drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did
    not restrict a certain length field, which allowed local
    users to gain privileges or cause a denial of service
    (heap-based buffer overflow) via an
    ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).

  - CVE-2016-7913: The xc2028_set_config function in
    drivers/media/tuners/tuner-xc2028.c in the Linux kernel
    allowed local users to gain privileges or cause a denial
    of service (use-after-free) via vectors involving
    omission of the firmware name from a certain data
    structure (bnc#1010478).

  - CVE-2016-7917: The nfnetlink_rcv_batch function in
    net/netfilter/nfnetlink.c in the Linux kernel did not
    check whether a batch message's length field is large
    enough, which allowed local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (infinite loop or out-of-bounds read) by
    leveraging the CAP_NET_ADMIN capability (bnc#1010444).

  - CVE-2016-8645: The TCP stack in the Linux kernel
    mishandled skb truncation, which allowed local users to
    cause a denial of service (system crash) via a crafted
    application that made sendto system calls, related to
    net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
    (bnc#1009969).

  - CVE-2016-8666: The IP stack in the Linux kernel allowed
    remote attackers to cause a denial of service (stack
    consumption and panic) or possibly have unspecified
    other impact by triggering use of the GRO path for
    packets with tunnel stacking, as demonstrated by
    interleaved IPv4 headers and GRE headers, a related
    issue to CVE-2016-7039 (bnc#1003964).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux
    kernel allowed local users to bypass integer overflow
    checks, and cause a denial of service (memory
    corruption) or have unspecified other impact, by
    leveraging access to a vfio PCI device file for a
    VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine
    confusion bug (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the
    Linux kernel misuses the kzalloc function, which allowed
    local users to cause a denial of service (integer
    overflow) or have unspecified other impact by leveraging
    access to a vfio PCI device file (bnc#1007197).

  - CVE-2016-9793: A bug in SO_{SND|RCV}BUFFORCE
    setsockopt() implementation was fixed, which allowed
    CAP_NET_ADMIN users to cause memory corruption.
    (bsc#1013531).

  - CVE-2016-9919: The icmp6_send function in
    net/ipv6/icmp.c in the Linux kernel omits a certain
    check of the dst data structure, which allowed remote
    attackers to cause a denial of service (panic) via a
    fragmented IPv6 packet (bnc#1014701).

The update package also includes non-security fixes. See advisory for
details.

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability
could set a socket's buffer size to be negative, leading to a denial
of service or other security impact. Additionally, in kernel versions
prior to 3.5, any user could do this if sysctl net.core.rmem_max was
changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability
attributes from any file visible to them, allowing a denial of
service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being
accessed through the SCSI generic (sg) driver led to a double- free,
possibly causing a denial of service (crash or memory corruption) or
privilege escalation. This could be exploited by local users with
permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a
use-after-free by the performance events (perf) subsystem, possibly
causing a denial of service (crash or memory corruption) or privilege
escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably
reset the terminal buffer state when the terminal line discipline was
changed. This could allow a local user with access to a terminal
device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its
set-group-ID flag, which should be done if the user changing it is not
a member of the group-owner. In some cases, this would allow the
user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while
handling a read of /proc/diskstats or /proc/partitions could lead to a
use-after-free, possibly causing a denial of service (crash or memory
corruption) or privilege escalation.

CVE-2016-7911

Dmitry Vyukov reported that a race between ioprio_get() and
ioprio_set() system calls could result in a use-after-free, possibly
causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of-
bounds memory access in the HID core. A physically present user could
possibly use this for denial of service (crash) or to leak sensitive
information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not
validate the length of packets to be sent. A user with permisson to
use ping sockets could cause an out-of-bounds read, possibly resulting
in a denial of service or information leak. However, on Debian systems
no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net)
did not validate the offset or length in link-layer fragmentation
headers. This allowed a remote system connected by Firewire to write
to memory after a packet buffer, leading to a denial of service
(crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached
to a TCP socket truncates or removes the TCP header, this could cause
a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets
(AF_PACKET family) had a race condition between enabling a transmit
ring buffer and changing the version of buffers used, which could
result in a use-after-free. A local user with the CAP_NET_ADMIN
capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead
to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not
validate 'out of the blue' packet chunk lengths early enough. A remote
system able could use this to cause a denial of service (crash) or
other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic
driver led to kernel memory corruption. Local users with permision to
access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or
i386) did not correctly handle the failure of certain instructions
that require software emulation on older processors. This could be
exploited by guest systems to leak sensitive information or for denial
of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem
that could result in a use-after-free. Local users with access to a
PCM sound device could exploit this for denial of service (crash or
memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.84-1. This version also includes bug fixes from upstream version
3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in
the performance events (perf) subsystem by disabling use by
unprivileged users. This can be done by setting sysctl
kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.39-1 which will be included in the next point release (8.6).

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2015-8963: Race condition in kernel/events/core.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect handling of an swevent data structure during a CPU unplug operation (bnc#1010502). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-7914: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel did not check whether a slot is a leaf, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures, as demonstrated by the keyutils test suite (bnc#1010475). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31349935 (bnc#1014746). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969). - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux kernel allowed local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a

This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly initialize the Code Segment (CS) in certain error cases. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2016-9756) Andrey Konovalov discovered that signed integer overflows existed in the setsockopt() system call when handling the SO_SNDBUFFORCE and SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service (system crash or memory corruption). (CVE-2016-9793) Baozeng Ding discovered a race condition that could lead to a use-after- free in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9794).

    descriptionThe SUSE Linux Enterprise 11 SP4 kernel was updated to 3.0.101-94 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-5551: tmpfs: clear S_ISGID when setting posix ACLs (bsc#1021258). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device NOTE: this vulnerability existed because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-5696: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#989152). - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provided an incomplete set of requirements for setattr operations that underspecified removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. (bnc#1014746). - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531). - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542). - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038). - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832). - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2013-6368: The KVM subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (bnc#853052). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467). - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
