According to the versions of the grub2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set- bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.(CVE-2024-1048)
Tenable has extracted the preceding description block directly from the EulerOS Virtualization grub2 security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
