EulerOS Virtualization 3.0.2.2 : systemd (EulerOS-SA-2020-1451)
high Nessus Plugin ID 135613
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the systemd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :- It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.(CVE-2018-16888)
- 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. Versions from v221 to v239 are vulnerable.(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. Affected releases are systemd versions up to and including 239.(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.
