| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-gke, linux-kvm, linux-raspi2, linux-snapdragon' package(s) announced via the USN-3485-1 advisory.
Vulnerability Insight:
It was discovered that a race condition existed in the ALSA subsystem of
the Linux kernel when creating and deleting a port via ioctl(). A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2017-15265)
Eric Biggers discovered that the key management subsystem in the Linux
kernel did not properly restrict adding a key that already exists but is
uninstantiated. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2017-15299)
It was discovered that a race condition existed in the packet fanout
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-2017-15649)
Eric Biggers discovered a race condition in the key management subsystem of
the Linux kernel around keys in a negative state. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-15951)
Andrey Konovalov discovered a use-after-free vulnerability in the USB
serial console driver in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2017-16525)
Andrey Konovalov discovered that the Ultra Wide Band driver in the Linux
kernel did not properly check for an error condition. A physically
proximate attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2017-16526)
Andrey Konovalov discovered that the ALSA subsystem in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2017-16527)
Andrey Konovalov discovered that the ALSA subsystem in the Linux kernel did
not properly validate USB audio buffer descriptors. A physically proximate
attacker could use this cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2017-16529)
Andrey Konovalov discovered that the USB unattached storage driver in the
Linux kernel contained out-of-bounds error when handling alternative
settings. A physically proximate attacker could use to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2017-16530)
Andrey Konovalov discovered that the USB subsystem in the Linux kernel did
not properly validate USB interface association descriptors. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2017-16531)
Andrey Konovalov discovered that the USB subsystem in the Linux kernel did
not properly validate USB HID descriptors. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2017-16533)
Andrey Konovalov discovered that the USB subsystem in the Linux ... [Please see the references for more information on the vulnerabilities]
