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

  - A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS     (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain     Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as     system availability. (CVE-2021-3672)

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.

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2022:2043 advisory.
