    <package name="net-fs/cifs-utils" auto="yes" arch="*">

  <description>
    <p>The mount.cifs utility had a shell injection issue where one can embed
      shell commands via the username mount option. Those commands will be run
      via popen() in the context of the user calling mount.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to use a specially crafted
      argument using mount.cifs, 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 LinuxCIFS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-fs/cifs-utils-6.11"
    </code>
