<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.

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.

|
|
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 ">=app-admin/usermin-1.090"
|
|
# emerge ">=app-admin/usermin-1.090"</code>
|
|
<p>
|
|
All Webmin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=app-admin/webmin-1.160"
|
|
# emerge ">=app-admin/webmin-1.160"</code>
|
|
