| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon' package(s) announced via the USN-4681-1 advisory.
Vulnerability Insight:
Ryan Hall discovered that the Intel 700 Series Ethernet Controllers driver
in the Linux kernel did not properly deallocate memory in some conditions.
A local attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-0148)
It was discovered that the console keyboard driver in the Linux kernel
contained a race condition. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2020-25656)
Minh Yuan discovered that the tty driver in the Linux kernel contained race
conditions when handling fonts. A local attacker could possibly use this to
expose sensitive information (kernel memory). (CVE-2020-25668)
Jinoh Kang discovered that the Xen event channel infrastructure in the
Linux kernel contained a race condition. An attacker in guest could
possibly use this to cause a denial of service (dom0 crash).
(CVE-2020-27675)
Minh Yuan discovered that the framebuffer console driver in the Linux
kernel did not properly handle fonts in some conditions. A local attacker
could use this to cause a denial of service (system crash) or possibly
expose sensitive information (kernel memory). (CVE-2020-28974)
It was discovered that Power 9 processors could be coerced to expose
information from the L1 cache in certain situations. A local attacker could
use this to expose sensitive information. (CVE-2020-4788)
