Subject: ipython3 may execute code from the current working directory

Summary: under certain circumstances, ipython3 may execute
code from the current working directory. This might be a
problem if the current working directory is not trusted.

python3 is safe.

Tested on ubuntu 20.

The following session illustrates it:

joro@...lokote:~/tests/dir2$ pwd
joro@...lokote:~/tests/dir2$ ipython3 --version
joro@...lokote:~/tests/dir2$ ls ~/tests/dir1  __pycache__
joro@...lokote:~/tests/dir2$ ls ~/tests/dir2  __pycache__
joro@...lokote:~/tests/dir2$ cat ~/tests/dir1/
try:  import joro
except:  print("error in import")
joro@...lokote:~/tests/dir2$ cat ~/tests/dir2/
print("imported joro :)")
joro@...lokote:~/tests/dir2$ ipython3 ~/tests/dir1/
imported joro :)
