  <background>
    <p>blktrace shows detailed information about what is happening on a block
      device IO queue.
    </p>
  </background>
  <description>
    <p>A crafted file could cause a buffer overflow in the ‘dev_map_read’
      function because the device and devno arrays are too small.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted file
      using blktrace, possibly resulting in execution of arbitrary code with
      the privileges of the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All blktrace users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose
      "&gt;=sys-block/blktrace-1.2.0_p20210419122502"
    </code>
