New! Plugin Severity Now Using CVSS v3

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has systemd packages installed that are affected by multiple vulnerabilities:

- 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)

- 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL systemd packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
