    <p>
    ViewCVS is a browser interface for viewing CVS and Subversion
    version control repositories through a web browser.
    </p>

  <description>
    <p>
    The tar export functions in ViewCVS bypass the 'hide_cvsroot' and
    'forbidden' settings and therefore expose information that should be
    kept secret (CAN-2004-0915). Furthermore, some error messages in
    ViewCVS do not filter user-provided information, making it vulnerable
    to a cross-site scripting attack (CAN-2004-1062).
    </p>
  </description>
  <impact type="low">
    <p>
    By using the tar export functions, a remote attacker could access
    information that is configured as restricted. Through the use of a
    malicious request, an attacker could also inject and execute malicious
    script code, potentially compromising another user's browser.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ViewCVS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/viewcvs-0.9.2_p20041207-r1&quot;</code>
  </resolution>
