Description

It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled.

Affected configurations

• systemd project systemd (< 242) • fedoraproject fedora 30 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.10 • netapp hci management node • netapp snapprotect • netapp solidfire • netapp cn1610 firmware
