  <background>
    <p>libqb is a library with the primary purpose of providing
      high-performance, reusable features for client-server architecture, such
      as logging, tracing, inter-process communication (IPC), and polling.
    </p>
  </background>
  <description>
    <p>It was discovered that libqb used predictable filenames (under /dev/shm
      and /tmp) without O_EXCL.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could perform symlink attacks to overwrite arbitrary
      files with the privileges of the user running the application linked
      against libqb.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libqb users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-cluster/libqb-1.0.5"
    </code>
