Problem description

Two vulnerabilities were discoverd by Stefen Esser in the cvs program. The first is an exploitable double free() bug within the server, which can be used to execute arbitray code on the CVS server. To accomplish this, the attacker must have an anonymous read-only login to the CVS server. The second vulnerability is with the Checkin-prog and Update-prog commands. If a client has write permission, he can use these commands to execute programs outside of the scope of CVS, the output of which will be sent as output to the client. This update fixes the double free() vulnerability and removes the Checkin-prog and Update-prog commands from CVS.
