Synopsis
========

Webmin contains two security vulnerabilities which could lead to a
Denial of Service attack and information disclosure.

Background
==========

Webmin is a web-based administration tool for Unix. It supports a wide
range of applications including Apache, DNS, file sharing and others.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /   Vulnerable   /                   Unaffected
    -------------------------------------------------------------------
  1  app-admin/webmin      <= 1.140-r1                        >= 1.150

Description
===========

Webmin contains two security vulnerabilities. One allows any user to
view the configuration of any module and the other could allow an
attacker to lock out a valid user by sending an invalid username and
password.

Impact
======

An authenticated user could use these vulnerabilities to view the
configuration of any module thus potentially obtaining important
knowledge about configuration settings. Furthermore an attacker could
lock out legitimate users by sending invalid login information.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Webmin users should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=app-admin/app-admin/webmin-1.150"
    # emerge ">=app-admin/app-admin/webmin-1.150"
