| Description: | Summary:
The remote host is missing an update for the 'linux-gcp, linux-hwe, linux-oem' package(s) announced via the USN-3617-2 advisory.
Vulnerability Insight:
USN-3617-1 fixed vulnerabilities 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.
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)
It was discovered that a use-after-free vulnerability existed in the
network namespaces 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-2017-15129)
Andrey Konovalov discovered that the usbtest device driver in the Linux
kernel did not properly validate endpoint metadata. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2017-16532)
Andrey Konovalov discovered that the SoundGraph iMON USB driver in the
Linux kernel did not properly validate device metadata. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2017-16537)
Andrey Konovalov discovered that the IMS Passenger Control Unit USB driver
in the Linux kernel did not properly validate device descriptors. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2017-16645)
Andrey Konovalov discovered that the DiBcom DiB0700 USB DVB driver in the
Linux kernel did not properly handle detach events. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2017-16646)
Andrey Konovalov discovered that the ASIX Ethernet USB driver in the Linux
kernel did not properly handle suspend and resume events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2017-16647)
Andrey Konovalov discovered that the CDC USB Ethernet driver did not
properly validate device descriptors. A physically proximate attacker could
use this to cause a denial of service (system crash). (CVE-2017-16649)
Andrey Konovalov discovered that the QMI WWAN USB driver did not properly
validate device descriptors. A physically proximate attacker could use this
to cause a denial of service (system crash). (CVE-2017-16650)
It was discovered that the HugeTLB component of the Linux kernel did not
properly handle holes in hugetlb ranges. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2017-16994)
It was discovered that the netfilter component of the Linux did not
properly restrict access to the connection ... [Please see the references for more information on the vulnerabilities]
