Description

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.

Affected configurations

• systemd project systemd (< 237) • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.10 • redhat enterprise linux 7.0 • netapp active iq performance analytics services • netapp element software
