The get_endpoints function in drivers/usb/misc/usbtest.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The get_endpoints function in drivers/usb/misc/usbtest.c in the Linux kernel through 4.13.11 allows local     users to cause a denial of service (NULL pointer dereference and system crash) or possibly have     unspecified other impact via a crafted USB device. (CVE-2017-16532)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - It was found that in the Linux kernel through     v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in     'block/bio.c' do unbalanced pages refcounting if IO     vector has small consecutive buffers belonging to the     same page. bio_add_pc_page() merges them into one, but     the page reference is never dropped, causing a memory     leak and possible system lockup due to out-of-memory     condition.(CVE-2017-12190)

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192)

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106)

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140)

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489)

  - The sg_ioctl() function in 'drivers/scsi/sg.c' in the     Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows     local users to obtain sensitive information from     uninitialized kernel heap-memory locations via an     SG_GET_REQUEST_TABLE ioctl call for     '/dev/sg0'.(CVE-2017-14991)

  - The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     before 4.8.1 allows local users (who are physically     proximate for inserting a crafted USB device) to gain     privileges by leveraging a write-what-where condition     that occurs after a race condition and a NULL pointer     dereference.(CVE-2017-15102)

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids     idr which could lead to double free and memory     corruption. This vulnerability could allow an     unprivileged local user to induce kernel memory     corruption on the system, leading to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although it is thought to be     unlikely.(CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel     oops).(CVE-2017-15274)

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299)

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649)

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525)

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526)

  - The sound/usb/mixer.c in the Linux kernel, before     4.13.8, allows local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16527)

  - The snd_usb_create_streams function in sound/usb/card.c     in the Linux kernel, before 4.13.6, allows local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)

  - The uas driver in the Linux kernel before 4.13.6 allows     local users to cause a denial of service (out-of-bounds     read and system crash), or possibly have unspecified     other impacts via a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)

  - The function drivers/usb/core/config.c in the Linux     kernel, allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION     descriptor.(CVE-2017-16531)

  - The get_endpoints function in     drivers/usb/misc/usbtest.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16532)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2018-0035 for details.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3619-2 advisory.

    USN-3619-1 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.

    Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel improperly     performed sign extension in some situations. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2017-16995)

    It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM     subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2017-0861)

    It was discovered that the KVM implementation in the Linux kernel allowed passthrough of the diagnostic     I/O port 0x80. An attacker in a guest VM could use this to cause a denial of service (system crash) in the     host OS. (CVE-2017-1000407)
