  <background>
    <p>International Components for Unicode (ICU) is a set of C/C++ and Java
      libraries providing Unicode and Globalization support for software
      applications.
    </p>
  </background>
  <description>
    <p>An error in the _canonicalize() function in uloc.cpp could cause a
      stack-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted locale
      representation using an application linked against ICU, 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 ICU users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/icu-49.1.1-r1"
    </code>
