CVE-2019-3844

It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow a cooperating process to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future when the GID will be recycled.

This issue did not affect the versions of systemd as shipped with Red Hat Enterprise Linux 7 as they did not include support for DynamicUser property.
