  <description>
    <p>It was discovered that Gentoo’s Asterisk ebuild does not properly set
      permissions on its data directories. This only affects OpenRC systems, as
      the flaw was exploitable via the init script.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could escalate privileges.</p>
  </impact>
  <workaround>
    <p>Users should ensure the proper permissions are set as discussed in the
      referenced bugs. Do not run /etc/init.d/asterisk checkperms.
    </p>
  </workaround>
  <resolution>
    <p>All Asterisk users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-misc/asterisk-13.32.0-r1"
    </code>
