According to the versions of the systemd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
It has been discovered that systemd-tmpfiles mishandles symbolic links present in non-terminal path components.
In some configurations a local user could use this vulnerability to get access to arbitrary files when the systemd-tmpfiles command is run.(CVE-2018-6954)
An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ‘:’. A local attacker can use this flaw to disclose process memory data.(CVE-2018-16866)
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. (CVE-2018-15686)
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.
