According to the versions of the systemd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • A vulnerability was found in systemd. This security flaw can cause a local information leak due to systemd-coredump not respecting the fs.suid_dumpable kernel setting. (CVE-2022-4415)

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.
