<title>Webmin: Information leak in Gentoo binary package</title>
<synopsis>

<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.

<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 &quot;&gt;=app-admin/webmin-1.170-r3&quot;</code>
