Subject: CVE request: f2py insecure temporary file use

Hello,

Jakub Wilk reported insecure temporary file use in f2py. From 
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737778>:

""
numpy/f2py/__init__.py contains this code:

      from numpy.distutils.exec_command import exec_command
      import tempfile
      if source_fn is None:
          fname = os.path.join(tempfile.mktemp()+'.f')
      else:
          fname = source_fn

      f = open(fname,'w')
""

Can a CVE please be assigned if one hasn't been already?
