    <p>
    Teemu Salmela discovered an error in the validation code of "smb://"
    URLs used by ELinks, the same issue as reported in GLSA 200612-16
    concerning Links.

  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to browse to a specially crafted
    "smb://" URL and execute arbitrary Samba commands, which would allow
    the overwriting of arbitrary local files or the upload or download of
    arbitrary files. This vulnerability can be exploited only if
    "smbclient" is installed on the victim's computer, which is provided by
    the "samba" Gentoo package.
    </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 "&gt;=www-client/elinks-0.11.2"</code>
  </resolution>
