| Description: | Summary:
The remote host is missing an update for the 'linux-lts-trusty' package(s) announced via the USN-3933-2 advisory.
Vulnerability Insight:
USN-3933-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 ESM.
It was discovered that an information leak vulnerability existed in the
Bluetooth implementation of the Linux kernel. An attacker within Bluetooth
range could possibly expose sensitive information (kernel memory).
(CVE-2017-1000410)
It was discovered that the USB serial device driver in the Linux kernel did
not properly validate baud rate settings when debugging is enabled. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-18360)
Mathias Payer and Hui Peng discovered a use-after-free vulnerability in the
Advanced Linux Sound Architecture (ALSA) subsystem. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2018-19824)
Shlomi Oberman, Yuli Shapiro, and Ran Menscher discovered an information
leak in the Bluetooth implementation of the Linux kernel. An attacker
within Bluetooth range could use this to expose sensitive information
(kernel memory). (CVE-2019-3459, CVE-2019-3460)
Jann Horn discovered that the KVM implementation in the Linux kernel
contained a use-after-free vulnerability. An attacker in a guest VM with
access to /dev/kvm could use this to cause a denial of service (guest VM
crash). (CVE-2019-6974)
Felix Wilhelm discovered that an information leak vulnerability existed in
the KVM subsystem of the Linux kernel, when nested virtualization is used.
A local attacker could use this to expose sensitive information (host
system memory to a guest VM). (CVE-2019-7222)
Jann Horn discovered that the mmap implementation in the Linux kernel did
not properly check for the mmap minimum address in some situations. A local
attacker could use this to assist exploiting a kernel NULL pointer
dereference vulnerability. (CVE-2019-9213)
Affected Software/OS:
