Summary

Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure.

"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.120 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2017-13166: An elevation of privilege vulnerability
    in the v4l2 video driver. (bnc#1072865).

  - CVE-2017-15951: The KEYS subsystem did not correctly
    synchronize the actions of updating versus finding a key
    in the 'negative' state to avoid a race condition, which
    allowed local users to cause a denial of service or
    possibly have unspecified other impact via crafted
    system calls (bnc#1062840 bnc#1065615).

  - CVE-2017-16644: The hdpvr_probe function in
    drivers/media/usb/hdpvr/hdpvr-core.c allowed local users
    to cause a denial of service (improper error handling
    and system crash) or possibly have unspecified other
    impact via a crafted USB device (bnc#1067118).

  - CVE-2017-16912: The 'get_pipe()' function
    (drivers/usb/usbip/stub_rx.c) allowed attackers to cause
    a denial of service (out-of-bounds read) via a specially
    crafted USB over IP packet (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function
    (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT
    packets allowed attackers to cause a denial of service
    (arbitrary memory allocation) via a specially crafted
    USB over IP packet (bnc#1078672).

  - CVE-2017-17975: Use-after-free in the usbtv_probe
    function in drivers/media/usb/usbtv/usbtv-core.c allowed
    attackers to cause a denial of service (system crash) or
    possibly have unspecified other impact by triggering
    failure of audio registration, because a kfree of the
    usbtv data structure occurs during a usbtv_video_free
    call, but the usbtv_video_fail label's code attempts to
    both access and free this data structure (bnc#1074426).

  - CVE-2017-18174: The amd_gpio_remove function in
    drivers/pinctrl/pinctrl-amd.c calls the
    pinctrl_unregister function, leading to a double free
    (bnc#1080533).

  - CVE-2017-18208: The madvise_willneed function in
    mm/madvise.c allowed local users to cause a denial of
    service (infinite loop) by triggering use of
    MADVISE_WILLNEED for a DAX mapping (bnc#1083494).

  - CVE-2018-1000026: A insufficient input validation
    vulnerability in bnx2x network card driver could result
    in DoS: Network card firmware assertion takes card
    off-line. This attack appear to be exploitable via An
    attacker on a must pass a very large, specially crafted
    packet to the bnx2x card. This can be done from an
    untrusted guest VM. (bnc#1079384).

  - CVE-2018-8087: Memory leak in the hwsim_new_radio_nl
    function in drivers/net/wireless/mac80211_hwsim.c
    allowed local users to cause a denial of service (memory
    consumption) by triggering an out-of-array error case
    (bnc#1085053).

  - CVE-2018-1068: Insufficient user provided offset
    checking in the ebtables compat code allowed local
    attackers to overwrite kernel memory and potentially
    execute code. (bsc#1085107)

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

    descriptionUSN-3653-1 fixed vulnerabilities and added mitigations in the Linux kernel for Ubuntu 17.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS. Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2018-3639) It was discovered that the netlink subsystem in the Linux kernel did not properly restrict observations of netlink messages to the appropriate net namespace. A local attacker could use this to expose sensitive information (kernel netlink traffic). (CVE-2017-17449) Tuba Yavuz discovered that a double-free error existed in the USBTV007 driver of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17975) It was discovered that a race condition existed in the Device Mapper component of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18203) It was discovered that an infinite loop could occur in the madvise(2) implementation in the Linux kernel in certain circumstances. A local attacker could use this to cause a denial of service (system hang). (CVE-2017-18208) Silvio Cesare discovered a buffer overwrite existed in the NCPFS implementation in the Linux kernel. A remote attacker controlling a malicious NCPFS server could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-8822). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control.(CVE-2018-18559i1/4%0 - The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump. A local users could obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-11472i1/4%0 - Race condition in net/packet/af_packet.c in the Linux kernel allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that makes PACKET_FANOUT setsockopt system calls.(CVE-2017-6346i1/4%0 - Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted application that uses shmctl IPC_RMID operations in conjunction with other shm system calls.(CVE-2013-7026i1/4%0 - An issue was discovered in the Linux kernel. A NULL pointer dereference and panic in hfsplus_lookup() in the fs/hfsplus/dir.c function can occur when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.(CVE-2018-14617i1/4%0 - The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.(CVE-2016-2782i1/4%0 - An information-exposure flaw was found in the Linux kernel where the pcpu_embed_first_chunk() function in mm/percpu.c allows local users to obtain kernel-object address information by reading the kernel log (dmesg). However, this address is not static and cannot be used to commit a further attack.(CVE-2018-5995i1/4%0 - Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket.(CVE-2014-6416i1/4%0 - It was found that the Linux kernel

    register action. Later, packet_release operates on only
    one of the two applicable linked lists. The attacker
    can achieve Program Counter control.(CVE-2018-18559i1/4%0

  - The acpi_ns_terminate() function in
    drivers/acpi/acpica/nsutils.c in the Linux kernel
    before 4.12 does not flush the operand cache and causes
    a kernel stack dump. A local users could obtain
    sensitive information from kernel memory and bypass the
    KASLR protection mechanism (in the kernel through 4.9)
    via a crafted ACPI table.(CVE-2017-11472i1/4%0

  - Race condition in net/packet/af_packet.c in the Linux
    kernel allows local users to cause a denial of service
    (use-after-free) or possibly have unspecified other
    impact via a multithreaded application that makes
    PACKET_FANOUT setsockopt system calls.(CVE-2017-6346i1/4%0

  - Multiple race conditions in ipc/shm.c in the Linux
    kernel before 3.12.2 allow local users to cause a
    denial of service (use-after-free and system crash) or
    possibly have unspecified other impact via a crafted
    application that uses shmctl IPC_RMID operations in
    conjunction with other shm system
    calls.(CVE-2013-7026i1/4%0

  - An issue was discovered in the Linux kernel. A NULL
    pointer dereference and panic in hfsplus_lookup() in
    the fs/hfsplus/dir.c function can occur when opening a
    file (that is purportedly a hard link) in an hfs+
    filesystem that has malformed catalog data, and is
    mounted read-only without a metadata
    directory.(CVE-2018-14617i1/4%0

  - The treo_attach function in drivers/usb/serial/visor.c
    in the Linux kernel before 4.5 allows physically
    proximate attackers to cause a denial of service (NULL
    pointer dereference and system crash) or possibly have
    unspecified other impact by inserting a USB device that
    lacks a (1) bulk-in or (2) interrupt-in
    endpoint.(CVE-2016-2782i1/4%0

  - An information-exposure flaw was found in the Linux
    kernel where the pcpu_embed_first_chunk() function in
    mm/percpu.c allows local users to obtain kernel-object
    address information by reading the kernel log (dmesg).
    However, this address is not static and cannot be used
    to commit a further attack.(CVE-2018-5995i1/4%0

  - Buffer overflow in net/ceph/auth_x.c in Ceph, as used
    in the Linux kernel before 3.16.3, allows remote
    attackers to cause a denial of service (memory
    corruption and panic) or possibly have unspecified
    other impact via a long unencrypted auth
    ticket.(CVE-2014-6416i1/4%0

  - It was found that the Linux kernel's ptrace subsystem
    allowed a traced process' instruction pointer to be set
    to a non-canonical memory address without forcing the
    non-sysret code path when returning to user space. A
    local, unprivileged user could use this flaw to crash
    the system or, potentially, escalate their privileges
    on the system.Note: The CVE-2014-4699 issue only
    affected systems using an Intel CPU.(CVE-2014-4699i1/4%0

  - The snd_compr_tstamp function in
    sound/core/compress_offload.c in the Linux kernel
    through 4.7, as used in Android before 2016-08-05 on
    Nexus 5 and 7 (2013) devices, does not properly
    initialize a timestamp data structure, which allows
    attackers to obtain sensitive information via a crafted
    application, aka Android internal bug 28770164 and
    Qualcomm internal bug CR568717.(CVE-2014-9892i1/4%0

  - A flaw was found in the way the Linux kernel's ext4
    file system handled the 'page size i1/4z block size'
    condition when the fallocate zero range functionality
    was used. A local attacker could use this flaw to crash
    the system.(CVE-2015-0275i1/4%0

  - An information leak flaw was found in the way the Linux
    kernel's ISO9660 file system implementation accessed
    data on an ISO9660 image with RockRidge Extension
    Reference (ER) records. An attacker with physical
    access to the system could use this flaw to disclose up
    to 255 bytes of kernel memory.(CVE-2014-9584i1/4%0

  - The pivot_root implementation in fs/namespace.c in the
    Linux kernel through 3.17 does not properly interact
    with certain locations of a chroot directory, which
    allows local users to cause a denial of service
    (mount-tree loop) via . (dot) values in both arguments
    to the pivot_root system call.(CVE-2014-7970i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel before
    4.8.12 does not properly initialize Code Segment (CS)
    in certain error cases, which allows local users to
    obtain sensitive information from kernel stack memory
    via a crafted application.(CVE-2016-9756i1/4%0

  - A flaw was found in the Linux kernel where the
    swiotlb_print_info() function in lib/swiotlb.c allows
    local users to obtain some kernel address information
    by reading the kernel log (dmesg). This address is not
    useful to commit a further attack.(CVE-2018-5953i1/4%0

  - A flaw was found in the way the Linux kernel's file
    system implementation handled rename operations in
    which the source was inside and the destination was
    outside of a bind mount. A privileged user inside a
    container could use this flaw to escape the bind mount
    and, potentially, escalate their privileges on the
    system.(CVE-2015-2925i1/4%0

  - A use-after-free fault in the Linux kernel's usbtv
    driver could allow an attacker to cause a denial of
    service (system crash), or have unspecified other
    impacts, by triggering failure of audio registration of
    USB hardware using the usbtv kernel
    module.(CVE-2017-17975i1/4%0

  - The mm subsystem in the Linux kernel through 4.10.10
    does not properly enforce the CONFIG_STRICT_DEVMEM
    protection mechanism, which allows local users to read
    or write to kernel memory locations in the first
    megabyte (and bypass slab-allocation access
    restrictions) via an application that opens the
    /dev/mem file, related to arch/x86/mm/init.c and
    drivers/char/mem.c.(CVE-2017-7889i1/4%0

  - A flaw was discovered in the way the kernel allows
    stackable filesystems to overlay. A local attacker who
    is able to mount filesystems can abuse this flaw to
    escalate privileges.(CVE-2014-9922i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1
    retains certain linked lists after a close or stop
    action, which allows local users to cause a denial of
    service (system crash) via a crafted ioctl call,
    related to the (1) snd_timer_close and (2)
    _snd_timer_stop functions.(CVE-2016-2548i1/4%0
