A successful attack requires that (a) the client has agreed + to allow the server to push configuration directives to it by including + "pull" or the macro "client" in its configuration file, (b) the client + succesfully authenticates the server, (c) the server is malicious or has + been compromised and is under the control of the attacker, and (d) the + client is running a non-Windows OS. Credit: David Wagner. + +* Miscellaneous defensive programming changes to multiple + areas of the code. In particular, use of the system() call + for calling executables such as ifconfig, route, and + user-defined scripts has been completely revamped in favor + of execve() on unix and CreateProcess() on Windows. + 2008.06.11 -- Version 2.1_rc8 * Added client authentication and packet filtering capability |
