"USN-3696-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

It was discovered that an integer overflow existed in the perf
subsystem of the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2017-18255)

Wei Fang discovered an integer overflow in the F2FS filesystem
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service. (CVE-2017-18257)

It was discovered that an information leak existed in the generic SCSI
driver in the Linux kernel. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2018-1000204)

It was discovered that the wait4() system call in the Linux kernel did
not properly validate its arguments in some situations. A local
attacker could possibly use this to cause a denial of service.
(CVE-2018-10087)

It was discovered that the kill() system call implementation in the
Linux kernel did not properly validate its arguments in some
situations. A local attacker could possibly use this to cause a denial
of service. (CVE-2018-10124)

Julian Stecklina and Thomas Prescher discovered that FPU register
states (such as MMX, SSE, and AVX registers) which are lazily restored
are potentially vulnerable to a side channel attack. A local attacker
could use this to expose sensitive information. (CVE-2018-3665)

Jakub Jirasek discovered that multiple use-after-errors existed in the
USB/IP implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2018-5814)

It was discovered that an information leak vulnerability existed in
the floppy driver in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory). (CVE-2018-7755)

Seunghun Han discovered an information leak in the ACPI handling code
in the Linux kernel when handling early termination of ACPI table
loading. A local attacker could use this to expose sensitive informal
(kernel address locations). (CVE-2017-13695)

It was discovered that a memory leak existed in the Serial Attached
SCSI (SAS) implementation in the Linux kernel. A physically proximate
attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2018-10021).

  script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - ALSA sequencer core initializes the event pool on
    demand by invoking snd_seq_pool_init() when the first
    write happens and the pool is empty. A user can reset
    the pool size manually via ioctl concurrently, and this
    may lead to UAF or out-of-bound access.(CVE-2018-7566)

  - The do_get_mempolicy() function in mm/mempolicy.c in
    the Linux kernel allows local users to hit a
    use-after-free bug via crafted system calls and thus
    cause a denial of service (DoS) or possibly have
    unspecified other impact. Due to the nature of the
    flaw, privilege escalation cannot be fully ruled
    out.(CVE-2018-10675)

  - The Linux kernel has an undefined behavior when an
    argument of INT_MIN is passed to the
    kernel/signal.c:kill_something_info() function. A local
    attacker may be able to exploit this to cause a denial
    of service.(CVE-2018-10124)

  - A an integer overflow vulnerability was discovered in
    the Linux kernel, from version 3.4 through 4.15, in the
    drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An
    attacker with access to the udldrmfb driver could
    exploit this to obtain full read and write permissions
    on kernel physical pages, resulting in a code execution
    in kernel space.(CVE-2018-8781)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c
    file in the Linux kernel allow a physically proximate
    attacker to cause a memory leak in the ATA command
    queue and, thus, denial of service by triggering
    certain failure conditions.(CVE-2018-10021)

  - A flaw was found in the Linux kernel's implementation
    of 32-bit syscall interface for bridging. This allowed
    a privileged user to arbitrarily write to a limited
    range of kernel memory.(CVE-2018-1068)

  - A vulnerability was found in the Linux kernel's
    kernel/events/core.c:perf_cpu_time_max_percent_handler(
    ) function. Local privileged users could exploit this
    flaw to cause a denial of service due to integer
    overflow or possibly have unspecified other
    impact.(CVE-2017-18255)

  - The kernel_wait4 function in kernel/exit.c in the Linux
    kernel, when an unspecified architecture and compiler
    is used, might allow local users to cause a denial of
    service by triggering an attempted use of the -INT_MIN
    value.(CVE-2018-10087)

  - A null pointer dereference in dccp_write_xmit()
    function in net/dccp/output.c in the Linux kernel
    allows a local user to cause a denial of service by a
    number of certain crafted system calls.(CVE-2018-1130)

  - An address corruption flaw was discovered in the Linux
    kernel built with hardware breakpoint
    (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a
    h/w breakpoint via 'modify_user_hw_breakpoint' routine,
    an unprivileged user/process could use this flaw to
    crash the system kernel resulting in DoS OR to
    potentially escalate privileges on a the
    system.(CVE-2018-1000199)

"Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a
supported upgrade path for systems that currently use kernel packages
from the 'jessie-backports' suite.

There is no need to upgrade systems using Linux 3.16, as that kernel
version will also continue to be supported in the LTS period.

This backport does not include the following binary packages :

hyperv-daemons libcpupower1 libcpupower-dev libusbip-dev
linux-compiler-gcc-4.9-x86 linux-cpupower linux-libc-dev usbip

Older versions of most of those are built from other source packages
in Debian 8.

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

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1
(bounds-check bypass) have been mitigated.

CVE-2017-18255

It was discovered that the performance events subsystem did not
properly validate the value of the kernel.perf_cpu_time_max_percent
sysctl. Setting a large value could have an unspecified security
impact. However, only a privileged user can set this sysctl.

CVE-2018-1118

The syzbot software found that the vhost driver did not initialise
message buffers which would later be read by user processes. A user
with access to the /dev/vhost-net device could use this to read
sensitive information from the kernel or other users' processes.

CVE-2018-1120

Qualys reported that a user able to mount FUSE filesystems can create
a process such that when another process attempting to read its
command line will be blocked for an arbitrarily long time. This could
be used for denial of service, or to aid in exploiting a race
condition in the other program.

CVE-2018-1130

The syzbot software found that the DCCP implementation of sendmsg()
does not check the socket state, potentially leading to a NULL pointer
dereference. A local user could use this to cause a denial of service
(crash). 

CVE-2018-3639

Multiple researchers have discovered that Speculative Store Bypass
(SSB), a feature implemented in many processors, could be used to read
sensitive information from another context. In particular, code in a
software sandbox may be able to read sensitive information from
outside the sandbox. This issue is also known as Spectre variant 4.

This update allows the issue to be mitigated on some x86
processors by disabling SSB. This requires an update to the
processor's microcode, which is non-free. It may be included
in an update to the system BIOS or UEFI firmware, or in a
future update to the intel-microcode or amd64-microcode
packages.

Disabling SSB can reduce performance significantly, so by
default it is only done in tasks that use the seccomp
feature. Applications that require this mitigation should
request it explicitly through the prctl() system call. Users
can control where the mitigation is enabled with the
spec_store_bypass_disable kernel parameter.

CVE-2018-5814

Jakub Jirasek reported race conditions in the USB/IP host driver. A
malicious client could use this to cause a denial of service (crash or
memory corruption), and possibly to execute code, on a USB/IP server.

CVE-2018-10021

A physically present attacker who unplugs a SAS cable can cause a
denial of service (memory leak and WARN).

CVE-2018-10087, CVE-2018-10124

zhongjiang found that the wait4() and kill() system call
implementations did not check for the invalid pid value of INT_MIN. If
a user passed this value, the behaviour of the code was formally
undefined and might have had a security impact.

CVE-2018-10853

Andy Lutomirski and Mika Penttilä reported that KVM for x86
processors did not perform a necessary privilege check when emulating
certain instructions. This could be used by an unprivileged user in a
guest VM to escalate their privileges within the guest.

CVE-2018-10876, CVE-2018-10877, CVE-2018-10878, CVE-2018-10879,
CVE-2018-10880, CVE-2018-10881, CVE-2018-10882, CVE-2018-10883

Wen Xu at SSLab, Gatech, reported that crafted ext4 filesystem images
could trigger a crash or memory corruption. A local user able to mount
arbitrary filesystems, or an attacker providing filesystems to be
mounted, could use this for denial of service or possibly for
privilege escalation.

CVE-2018-10940

Dan Carpenter reported that the optical disc driver (cdrom) does not
correctly validate the parameter to the CDROM_MEDIA_CHANGED ioctl. A
user with access to a cdrom device could use this to cause a denial of
service (crash).

CVE-2018-11506

Piotr Gabriel Kosinski and Daniel Shapira reported that the SCSI
optical disc driver (sr) did not allocate a sufficiently large buffer
for sense data. A user with access to a SCSI optical disc device that
can produce more than 64 bytes of sense data could use this to cause a
denial of service (crash or memory corruption), and possibly for
privilege escalation.

CVE-2018-12233

Shankara Pailoor reported that a crafted JFS filesystem image could
trigger a denial of service (memory corruption). This could possibly
also be used for privilege escalation.

CVE-2018-1000204

The syzbot software found that the SCSI generic driver (sg) would in
some circumstances allow reading data from uninitialised buffers,
which could include sensitive information from the kernel or other
tasks. However, only privileged users with the CAP_SYS_ADMIN or
CAP_SYS_RAWIO capability were allowed to do this, so this has little
or no security impact.

For Debian 8 'Jessie', these problems have been fixed in version
4.9.110-1~deb8u1. This update additionally fixes Debian bugs #860900,
#872907, #892057, #896775, #897590, and #898137; and includes many
more bug fixes from stable updates 4.9.89-4.9.110 inclusive.

We recommend that you upgrade your linux-4.9 packages.

"It was discovered that an integer overflow existed in the perf
subsystem of the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2017-18255)

Wei Fang discovered an integer overflow in the F2FS filesystem
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service. (CVE-2017-18257)

It was discovered that an information leak existed in the generic SCSI
driver in the Linux kernel. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2018-1000204)

It was discovered that the wait4() system call in the Linux kernel did
not properly validate its arguments in some situations. A local
attacker could possibly use this to cause a denial of service.
(CVE-2018-10087)

It was discovered that the kill() system call implementation in the
Linux kernel did not properly validate its arguments in some
situations. A local attacker could possibly use this to cause a denial
of service. (CVE-2018-10124)

Julian Stecklina and Thomas Prescher discovered that FPU register
states (such as MMX, SSE, and AVX registers) which are lazily restored
are potentially vulnerable to a side channel attack. A local attacker
could use this to expose sensitive information. (CVE-2018-3665)

Jakub Jirasek discovered that multiple use-after-errors existed in the
USB/IP implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2018-5814)

It was discovered that an information leak vulnerability existed in
the floppy driver in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory). (CVE-2018-7755)

Seunghun Han discovered an information leak in the ACPI handling code
in the Linux kernel when handling early termination of ACPI table
loading. A local attacker could use this to expose sensitive informal
(kernel address locations). (CVE-2017-13695)

It was discovered that a memory leak existed in the Serial Attached
SCSI (SAS) implementation in the Linux kernel. A physically proximate
attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2018-10021).
