Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1510 advisory.

Insufficient control flow management in BIOS firmware for 8th, 9th, 10th Generation Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 & 5000 Series Processors may allow an authenticated user to potentially enable denial of service via adjacent access. (CVE-2019-14558)

Memory leak in ArpOnFrameRcvdDpc (CVE-2019-14559)

Numeric truncation in MdeModulePkg/PiDxeS3BootScriptLib (CVE-2019-14563)

DxeImageVerificationHandler() fails open in case of dbx signature check (CVE-2019-14575)

Potential use-after-free due to the original configuration runtime memory is freed but it is still exposed to the OS runtime (CVE-2019-14586)

Double-unmap issue in SdMmcCreateTrb function in MdeModulePkg/Bus/Pci/SdMmcPciHcDxe/SdMmcPciHci.c (CVE-2019-14587)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update edk2' to update your system.
