    <p>A remote attacker could entice a user to open a specially crafted
      archive using Ark, possibly resulting in execution of arbitrary code with
      the privileges of the process or a Denial of Service condition.

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=kde-apps/ark-20.04.3-r1"
