CVE-2012-2983, CVE-2012-4893, SA51201).

The 1.680 version fixed security issues that could be exploited by
un-trusted Webmin users in the PHP Configuration and Webalizer
modules.

The Authen::Libwrap perl module used by Webmin is also being provided.

The updated packages have been upgraded to the 1.680 version which is
not vulnerable to these issues."
