Dear All, Execution Flow Control (EFC) is available for download at http://sourceforge.net/projects/efc/ What is EFC? EFC monitors the execution of a program by observing system calls madeby the program. EFC generates a database for each program describing its behavioral model. The moment request for execution of a program ismade, kernel also loads program's behavioral model into the memory. Each request by a program is compared with model data base, if requestagrees with model it is permitted else program is killed.EFC is a kernel module, and woks on Linux only.

Hi Bal,Although I appriciate ideas to enhance security concerning buffer overflows or format string bugs, i cannot understand why to find
the following lines in etc_db_new.c including your package: <snip> char pwd[MAX_PATH_LEN]; ... i = 0; while((ch = fgetc(strace_file)) != '\0') { pwd[i] = ch; i++; } ... </snip>Haven't found any made borders. And yes, due to its permissions it won't let people become root ... it is just a cosmetic failure. (hopefully) :)
Moreover, and that is the actual reason for replying your mail ...I couldn't find the patch in $EFC_PATH/efc/ ... did I just download a non complete package?
