    URLs when it runs smbclient commands.

  <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 the 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 Links users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-client/links-2.1_pre26&quot;</code>
  </resolution>
