"The remote EulerOS Virtualization for ARM 64 host is missing multiple security
updates.");
  script_set_attribute(attribute:"description", value:
"According 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 :

  - The kernel package contains the Linux kernel (vmlinuz),
    the core of any Linux operating system. The kernel
    handles the basic functions of the operating system:
    memory allocation, process allocation, device input and
    output, etc.Security Fix(es):A flaw named FragmentSmack
    was found in the way the Linux kernel handled
    reassembly of fragmented IPv4 and IPv6 packets. A
    remote attacker could use this flaw to trigger time and
    calculation expensive fragment reassembly algorithm by
    sending specially crafted packets which could lead to a
    CPU saturation and hence a denial of service on the
    system.(CVE-2018-5391)Multiple out-of-bounds write
    flaws were found in the way the Cherry Cymotion
    keyboard driver, KYE/Genius device drivers, Logitech
    device drivers, Monterey Genius KB29E keyboard driver,
    Petalynx Maxter remote control driver, and Sunplus
    wireless desktop driver handled HID reports with an
    invalid report descriptor size. An attacker with
    physical access to the system could use either of these
    flaws to write data past an allocated memory
    buffer.(CVE-2014-3184)The __get_data_block function in
    fs/f2fs/data.c in the Linux kernel before 4.11 allows
    local users to cause a denial of service (integer
    overflow and loop) via crafted use of the open and
    fallocate system calls with an FS_IOC_FIEMAP
    ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux
    kernel through 4.14.4 does not require the
    CAP_NET_ADMIN capability for add_callback and
    remove_callback operations. This allows local users to
    bypass intended access restrictions because the
    xt_osf_fingers data structure is shared across all
    network namespaces.(CVE-2017-17450)A denial of service
    flaw was discovered in the Linux kernel, where a race
    condition caused a NULL pointer dereference in the RDS
    socket-creation code. A local attacker could use this
    flaw to create a situation in which a NULL pointer
    crashed the kernel.(CVE-2015-7990)An issue was
    discovered in the Linux kernel before 4.19.9. The USB
    subsystem mishandles size checks during the reading of
    an extra descriptor, related to
    __usb_get_extra_descriptor in
    drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in
    the Linux kernel before 4.1.4 mishandles anonymous
    pages, which allows local users to gain privileges or
    cause a denial of service (page tainting) via a crafted
    application that triggers writing to page
    zero.(CVE-2015-3288)The ovl_setattr function in
    fs/overlayfs/inode.c in the Linux kernel through 4.3.3
    attempts to merge distinct setattr operations, which
    allows local users to bypass intended access
    restrictions and modify the attributes of arbitrary
    overlay files via a crafted
    application.(CVE-2015-8660)A flaw was found in the
    Linux kernel where a local user with a shell account
    can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could
    create an invalid inode variable, leading to a kernel
    panic.(CVE-2017-15128)An integer overflow flaw was
    found in the way the lzo1x_decompress_safe() function
    of the Linux kernel's LZO implementation processed
    Literal Runs. A local attacker could, in extremely rare
    cases, use this flaw to crash the system or,
    potentially, escalate their privileges on the
    system.(CVE-2014-4608)It was found that Linux kernel's
    ptrace subsystem did not properly sanitize the
    address-space-control bits when the program-status word
    (PSW) was being set. On IBM S/390 systems, a local,
    unprivileged user could use this flaw to set
    address-space-control bits to the kernel space, and
    thus gain read and write access to kernel
    memory.(CVE-2014-3534)A use-after-free flaw was found
    in the Linux kernel's file system encryption
    implementation. A local user could revoke keyring keys
    being used for ext4, f2fs, or ubifs encryption, causing
    a denial of service on the system.(CVE-2017-7374)The
    usbip_recv_xbuff function in
    drivers/usb/usbip/usbip_common.c in the Linux kernel
    before 4.5.3 allows remote attackers to cause a denial
    of service (out-of-bounds write) or possibly have
    unspecified other impact via a crafted length value in
    a USB/IP packet.(CVE-2016-3955)A flaw was found in the
    patches used to fix the 'dirtycow' vulnerability
    (CVE-2016-5195). An attacker, able to run local code,
    can exploit a race condition in transparent huge pages
    to modify usually read-only huge
    pages.(CVE-2017-1000405)The aio_mount function in
    fs/aio.c in the Linux kernel does not properly restrict
    execute access, which makes it easier for local users
    to bypass intended SELinux W^X policy
    restrictions.(CVE-2016-10044)The Serial Attached SCSI
    (SAS) implementation in the Linux kernel mishandles a
    mutex within libsas. This allows local users to cause a
    denial of service (deadlock) by triggering certain
    error-handling code.(CVE-2017-18232)A use-after-free
    vulnerability was found in tcp_xmit_retransmit_queue
    and other tcp_* functions. This condition could allow
    an attacker to send an incorrect selective
    acknowledgment to existing connections, possibly
    resetting a connection.(CVE-2016-6828)The instruction
    decoder in arch/x86/kvm/emulate.c in the KVM subsystem
    in the Linux kernel before 3.18-rc2 does not properly
    handle invalid instructions, which allows guest OS
    users to cause a denial of service (NULL pointer
    dereference and host OS crash) via a crafted
    application that triggers (1) an improperly fetched
    instruction or (2) an instruction that occupies too
    many bytes. NOTE: this vulnerability exists because of
    an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The
    snd_compress_check_input function in
    sound/core/compress_offload.c in the ALSA subsystem in
    the Linux kernel before 3.17 does not properly check
    for an integer overflow, which allows local users to
    cause a denial of service (insufficient memory
    allocation) or possibly have unspecified other impact
    via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl
    call.(CVE-2014-9904)The resv_map_release function in
    mm/hugetlb.c in the Linux kernel, through 4.15.7,
    allows local users to cause a denial of service (BUG)
    via a crafted application that makes mmap system calls
    and has a large pgoff argument to the remap_file_pages
    system call.(CVE-2018-7740)

"The remote EulerOS Virtualization host is missing multiple security
updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - A flaw was found in the way the Linux kernel's SCTP
    implementation validated INIT chunks when performing
    Address Configuration Change (ASCONF). A remote
    attacker could use this flaw to crash the system by
    sending a specially crafted SCTP packet to trigger a
    NULL pointer dereference on the system.(CVE-2014-7841)

  - It was found that reporting emulation failures to user
    space could lead to either a local (CVE-2014-7842) or a
    L2-i1/4zL1 (CVE-2010-5313) denial of service. In the case
    of a local denial of service, an attacker must have
    access to the MMIO area or be able to access an I/O
    port. Please note that on certain systems, HPET is
    mapped to userspace as part of vdso (vvar) and thus an
    unprivileged user may generate MMIO transactions (and
    enter the emulator) this way.(CVE-2014-7842)

  - 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-2014-7970)

  - The do_umount function in fs/namespace.c in the Linux
    kernel through 3.17 does not require the CAP_SYS_ADMIN
    capability for do_remount_sb calls that change the root
    filesystem to read-only, which allows local users to
    cause a denial of service (loss of writability) by
    making certain unshare system calls, clearing the /
    MNT_LOCKED flag, and making an MNT_FORCE umount system
    call.(CVE-2014-7975)

  - A race condition flaw was found in the Linux kernel's
    ext4 file system implementation that allowed a local,
    unprivileged user to crash the system by simultaneously
    writing to a file and toggling the O_DIRECT flag using
    fcntl(F_SETFL) on that file.(CVE-2014-8086)

  - A flaw was found in the way the Linux kernel's
    netfilter subsystem handled generic protocol tracking.
    As demonstrated in the Stream Control Transmission
    Protocol (SCTP) case, a remote attacker could use this
    flaw to bypass intended iptables rule restrictions when
    the associated connection tracking module was not
    loaded on the system.(CVE-2014-8160)

  - It was found that due to excessive files_lock locking,
    a soft lockup could be triggered in the Linux kernel
    when performing asynchronous I/O operations. A local,
    unprivileged user could use this flaw to crash the
    system.(CVE-2014-8172)

  - A NULL pointer dereference flaw was found in the way
    the Linux kernel's madvise MADV_WILLNEED functionality
    handled page table locking. A local, unprivileged user
    could use this flaw to crash the system.(CVE-2014-8173)

  - It was found that the fix for CVE-2014-3601 was
    incomplete: the Linux kernel's kvm_iommu_map_pages()
    function still handled IOMMU mapping failures
    incorrectly. A privileged user in a guest with an
    assigned host device could use this flaw to crash the
    host.(CVE-2014-8369)

  - The instruction decoder in arch/x86/kvm/emulate.c in
    the KVM subsystem in the Linux kernel before 3.18-rc2
    lacks intended decoder-table flags for certain
    RIP-relative instructions, which allows guest OS users
    to cause a denial of service (NULL pointer dereference
    and host OS crash) via a crafted
    application.(CVE-2014-8480)

  - The instruction decoder in arch/x86/kvm/emulate.c in
    the KVM subsystem in the Linux kernel before 3.18-rc2
    does not properly handle invalid instructions, which
    allows guest OS users to cause a denial of service
    (NULL pointer dereference and host OS crash) via a
    crafted application that triggers (1) an improperly
    fetched instruction or (2) an instruction that occupies
    too many bytes. NOTE: this vulnerability exists because
    of an incomplete fix for CVE-2014-8480.(CVE-2014-8481)

  - A flaw was found in the way the Linux kernel's VFS
    subsystem handled file system locks. A local,
    unprivileged user could use this flaw to trigger a
    deadlock in the kernel, causing a denial of service on
    the system.(CVE-2014-8559)

  - An information leak flaw was found in the Linux
    kernel's IEEE 802.11 wireless networking
    implementation. When software encryption was used, a
    remote attacker could use this flaw to leak up to 8
    bytes of plaintext.(CVE-2014-8709)

  - A stack-based buffer overflow flaw was found in the
    TechnoTrend/Hauppauge DEC USB device driver. A local
    user with write access to the corresponding device
    could use this flaw to crash the kernel or,
    potentially, elevate their privileges on the
    system.(CVE-2014-8884)

  - The do_double_fault function in arch/x86/kernel/traps.c
    in the Linux kernel through 3.17.4 does not properly
    handle faults associated with the Stack Segment (SS)
    segment register, which allows local users to cause a
    denial of service (panic) via a modify_ldt system call,
    as demonstrated by sigreturn_32 in the
    linux-clock-tests test suite.(CVE-2014-9090)

  - A flaw was found in the way the Linux kernel handled GS
    segment register base switching when recovering from a
    #SS (stack segment) fault on an erroneous return to
    user space. A local, unprivileged user could use this
    flaw to escalate their privileges on the
    system.(CVE-2014-9322)

  - An information leak flaw was found in the way the Linux
    kernel changed certain segment registers and
    thread-local storage (TLS) during a context switch. A
    local, unprivileged user could use this flaw to leak
    the user space TLS base address of an arbitrary
    process.(CVE-2014-9419)

  - It was found that the Linux kernel's ISO file system
    implementation did not correctly limit the traversal of
    Rock Ridge extension Continuation Entries (CE). An
    attacker with physical access to the system could use
    this flaw to trigger an infinite loop in the kernel,
    resulting in a denial of service.(CVE-2014-9420)

  - A race condition flaw was found in the way the Linux
    kernel keys management subsystem performed key garbage
    collection. A local attacker could attempt accessing a
    key while it was being garbage collected, which would
    cause the system to crash.(CVE-2014-9529)

  - 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-2014-9584)

  - An information leak flaw was found in the way the Linux
    kernel's Virtual Dynamic Shared Object (vDSO)
    implementation performed address randomization. A
    local, unprivileged user could use this flaw to leak
    kernel memory addresses to user-space.(CVE-2014-9585)
