A heap use-after-free flaw in systemd at worst might allow an attacker to execute arbitrary code.

A system and service manager.
It was found that systemd incorrectly handled certain Polkit queries.
A local unprivileged user, by sending a specially crafted Polkit query, could possibly execute arbitrary code with the privileges of the process, escalate privileges or cause a Denial of Service condition.
There is no known workaround at this time.
All systemd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/systemd-244.3"
