  <title>Webmin, Usermin: Multiple vulnerabilities in Usermin</title>
  <synopsis>
    A vulnerability in the webmail function of Usermin could be used by an
    attacker to execute shell code via a specially-crafted e-mail. A bug in the
    installation script of Webmin and Usermin also allows a local user to
    execute a symlink attack at installation time.

    <p>
    Webmin and Usermin are web-based system administration consoles. Webmin
    allows an administrator to easily configure servers and other features.
    Usermin allows users to configure their own accounts, execute commands,
    and read e-mail. The Usermin functionality, including webmail, is also
    included in Webmin.

  <description>
    <p>
    There is an input validation bug in the webmail feature of Usermin.
    </p>
    <p>
    Additionally, the Webmin and Usermin installation scripts write to
    /tmp/.webmin without properly checking if it exists first.
    </p>

  <impact type="normal">
    <p>
    The first vulnerability allows a remote attacker to inject arbitrary
    shell code in a specially-crafted e-mail. This could lead to remote
    code execution with the privileges of the user running Webmin or
    Usermin.
    </p>
    <p>
    The second could allow local users who know Webmin or Usermin is going
    to be installed to have arbitrary files be overwritten by creating a
    symlink by the name /tmp/.webmin that points to some target file, e.g.
    /etc/passwd.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Usermin users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=app-admin/usermin-1.090"
    # emerge "&gt;=app-admin/usermin-1.090"</code>
    <p>
    All Webmin users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=app-admin/webmin-1.160"
    # emerge "&gt;=app-admin/webmin-1.160"</code>
  </resolution>
