Webmin is a web-based interface for Unix-like systems. Usermin is
|
|
a simplified version of Webmin designed for use by normal users rather
|
|
than system administrators.

Jack Louis discovered that the Webmin and Usermin "miniserv.pl"
|
|
web server component is vulnerable to a Perl format string
|
|
vulnerability. Login with the supplied username is logged via the Perl
|
|
"syslog" facility in an unsafe manner.

|
<impact type="high">
|
|
<p>
|
|
A remote attacker can trigger this vulnerability via a specially
|
|
crafted username containing format string data. This can be exploited
|
|
to consume a large amount of CPU and memory resources on a vulnerable
|
|
system, and possibly to execute arbitrary code of the attacker's choice
|
|
with the permissions of the user running Webmin.
|
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>

<resolution>

<p>
|
|
All Webmin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/webmin-1.250"</code>
|
|
<p>
|
|
All Usermin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/usermin-1.180"</code>
|
|
</resolution>
