+  <title>Webmin, Usermin: Remote code execution through PAM authentication</title>
+  <synopsis>
+    If Webmin or Usermin is configured to use full PAM conversations, it is
+    vulnerable to the remote execution of arbitrary code with root privileges.

+  <background>
+    <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-mails.
+    </p>
+  </background>
+  <description>
+    <p>
+    Keigo Yamazaki discovered that the miniserv.pl webserver, used in
+    both Webmin and Usermin, does not properly validate authentication
+    credentials before sending them to the PAM (Pluggable Authentication
+    Modules) authentication process. The default configuration shipped with
+    Gentoo does not enable the "full PAM conversations" option and is
+    therefore unaffected by this flaw.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could bypass the authentication process and run
+    any command as the root user on the target server.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    Do not enable "full PAM conversations" in the Authentication
+    options of Webmin and Usermin.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Webmin users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-admin/webmin-1.230"</code>
+    <p>
+    All Usermin users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-admin/usermin-1.160"</code>
+  </resolution>
