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?
Regards,
Matthias Stiller
