| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon' package(s) announced via the USN-3910-1 advisory.
Vulnerability Insight:
It was discovered that the f2fs filesystem implementation in the Linux
kernel did not handle the noflush_merge mount option correctly. An attacker
could use this to cause a denial of service (system crash).
(CVE-2017-18241)
It was discovered that the procfs filesystem did not properly handle
processes mapping some memory elements onto files. A local attacker could
use this to block utilities that examine the procfs filesystem to report
operating system state, such as ps(1). (CVE-2018-1120)
Hui Peng and Mathias Payer discovered that the Option USB High Speed driver
in the Linux kernel did not properly validate metadata received from the
device. A physically proximate attacker could use this to cause a denial of
service (system crash). (CVE-2018-19985)
It was discovered that multiple integer overflows existed in the hugetlbfs
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2018-7740)
Jann Horn discovered a race condition in the fork() system call in the
Linux kernel. A local attacker could use this to gain access to services
that cache authorizations. (CVE-2019-6133)
Affected Software/OS:
