  script_tag(name:"vuldetect", value:"Checks if a vulnerable package version is present on the target host.");

  script_tag(name:"insight", value:"This update is based on upstream 5.4.17 and fixes at least the following
security vulnerabilities:

In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel
may be able to read memory locations from another process in the same guest.
This problem is limit to the host running linux kernel 4.10 with a guest
running linux kernel 4.16 or later. The problem mainly affects AMD
processors but Intel CPUs cannot be ruled out (CVE-2019-3016).

A heap-based buffer overflow vulnerability was found in the Linux kernel,
in Marvell WiFi chip driver. A remote attacker could cause a denial of
service (system crash) or, possibly execute arbitrary code, when the
lbs_ibss_join_existing function is called after a STA connects to an AP
(CVE-2019-14896).

A stack-based buffer overflow was found in the Linux kernel, in Marvell
WiFi chip driver. An attacker is able to cause a denial of service
(system crash) or, possibly execute arbitrary code, when a STA works in
IBSS mode (allows connecting stations together without the use of an AP)
and connects to another STA (CVE-2019-14897).

fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky
use-after-free, which allows local users to cause a denial of service
(OOPS) or possibly obtain sensitive information from kernel memory, aka
CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX
domain socket, if the socket is being moved to a new parent directory and
its old parent directory is being removed (CVE-2020-8428).

arm64/KVM debug registers vulnerability affecting systems with an ARMv8.1
or later CPU (with the Virtualisation Host Extensions). The implications
are that a guest, for a brief period, may be able to read event counters
belonging to the host or potentially trigger perf-related IRQs in the host
(no CVE assigned yet).

There is also various fixes for crashing or hanging the kernel by malicious
users or devices.

Other additional fixes and features in this update:

- WireGuard kernel module has been updated to 0.0.20200128 and the tools
 has been updated to 1.0.20200121.

- platform/x86: asus_wmi: Support throttle thermal policy, and set to
 default to avoid overheating and throttling

- hwmon/k10temp: Support for additional temperature sensors as well as
 voltage and current telemetry for Zen CPUs

- hid: add Amd Sensor Fusion Hub Driver

- e1000e: Revert 'e1000e: Make watchdog use delayed work' as it causes
 issues on some systems
- e1000e: Add support for Comet Lake and Tiger Lake

- x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode
 (fixing PIT not being setup on some systems)

- cifs: fix soft mounts hanging in the reconnect code

- move kernel preun bits to postun to fix grub2 menu cleanup on kernel
 uninstall (mga#16268)

For other upstream fixes in this update, see the referenced changelogs.");
