  <description>
    <p>
    Arnaud Giersch discovered that the "add_filename_to_string()" function
    in file intl/gettext/loadmsgcat.c uses an untrusted relative path,
    allowing for a format string attack with a malicious .po file.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could entice a user to run ELinks in a specially
    crafted directory environment containing a malicious ".po" file,
    possibly resulting in the execution of arbitrary code with the
    privileges of the user running ELinks.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ELinks users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-client/elinks-0.11.2-r1&quot;</code>
  </resolution>
