According to the versions of the edk2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
Insufficient control flow management in BIOS firmware for 8th, 9th, 10th Generation Intelยฎ Coreโข, Intelยฎ Celeronยฎ Processor 4000 & 5000 Series Processors may allow an authenticated user to potentially enable denial of service via adjacent access. (CVE-2019-14558)
Use after free vulnerability in EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via adjacent access. (CVE-2019-14586)
Logic issue EDK II may allow an unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2019-14587)
An unlimited recursion in DxeCore in EDK II. (CVE-2021-28210)
Existing CommBuffer checks in SmmEntryPoint will not catch underflow when computing BufferSize.
(CVE-2021-38578)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
