Description Vincent Danen 2011-10-20 16:13:27 EDT

A Cross-Site Request Forgery (CSRF) flaw was found in FreeIPA due to a lack of checking the Referer Header in the server (it is not set in the CLI utilities).  If a remote attacker could trick a user, who was logged into the FreeIPA management interface, into visiting a specially-crafted URL, the attacker could perform FreeIPA oonfiguration changes with the privileges of the logged in user.

Added Nalin as he is the maintainer of the certmonger package.

Require a Referer in the server, send one in the clients

The xmlrpc-c api does not seem to provide a way to set arbitrary headers. It does allow you to set the user-agent string though, so we set that with an embedded line-feed (\n) and a Referer entry. It isn't pretty but it works.

Updated certmonger patch to address Nalin's concerns

I added #define _GNU_SOURCE so asprintf() gets defined. I think this should be benign but you know certmonger better than I.
