Hi, I have a couple of question that dont allow me to sleep properly.
here we go:
1. is this suid root code exploitable with a buffer overflow technique:
/* foo.c */
main(int argc, char *argv[]){
...
setuid(0)
...
if ( ((strcmp(argv[i],"foo")) == 0)
|| ((strcmp(argv[i],"bar")) == 0) )
....
}
2. how can I redirect stderr to /dev/null? for example when I am 'finding' a
file in the whole dir tree I dont want to look at the "permised denied"
warning.
ej: find / -name "foo" -print > /dev/null & <--- how to redict stderr
that's all for now....
