Title:
  pydoc.py uses old netscape navigator

Status in python2.7 package in Ubuntu:
  New

Bug description:
  File :
  /usr/lib/python2.7/pydoc.py

  line : 2216 ... 2226

  pydoc.py uses old netscape navigator when the webbrowser module can
  not be imported:

  And it is vulnerable to shell command injection too,
  because it uses os.system() wich allows shell commands in the parameter "url".

  code :

          def open(self, event=None, url=None):
              url = url or self.server.url
              try:
                  import webbrowser
                  webbrowser.open(url)
              except ImportError: # pre-webbrowser.py compatibility
                  if sys.platform == 'win32':
                      os.system('start "%s"' % url)
                  else:
                      rc = os.system('netscape -remote "openURL(%s)" &' % url)
                      if rc: os.system('netscape "%s" &' % url)
