  <title>Webmin: Information leak in Gentoo binary package</title>
  <synopsis>
    Portage-built Webmin binary packages accidentally include a file containing
    the local encrypted root password.

  <affected>
    <package name="app-admin/webmin" auto="yes" arch="*">

    <p>
    Webmin is a web-based system administration console allowing an
    administrator to easily configure servers and other features. Using the
    'buildpkg' FEATURE, or the -b/-B emerge options, Portage can build
    reusable binary packages for any of the packages available through the
    Portage tree.
    </p>

  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that
    the Webmin ebuild contains a design flaw. It imports the encrypted
    local root password into the miniserv.users file before building binary
    packages that include this file.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could retrieve Portage-built Webmin binary packages
    and recover the encrypted root password from the build host.
    </p>
  </impact>
  <workaround>
    <p>
    Users who never built or shared a Webmin binary package are unaffected
    by this.
    </p>
  </workaround>
  <resolution>
    <p>
    Webmin users should delete any old shared Webmin binary package as soon
    as possible. They should also consider their buildhost root password
    potentially exposed and follow proper audit procedures.
    </p>
    <p>
    If you plan to build binary packages, you should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/webmin-1.170-r3"</code>
