EulerOS Virtualization 2.9.0 : edk2 (EulerOS-SA-2021-1764)

medium Nessus Plugin ID 148590
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the edk2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- Integer overflow in DxeImageVerificationHandler() EDK II may allow an authenticated user to potentially enable denial of service via local access.(CVE-2019-14562)

- The LzmaUefiDecompressGetInfo function fetches 8 bytes (64bit-wide) of the uncompressed data size from the LZMA header then silently drops the upper 32bit by casting it to UINT32.(CVE-2021-28211)

- edk2: unlimited FV recursion, round 2.(CVE-2021-28210)

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.

Solution

Update the affected edk2 packages.
