New submission from Anders Hammarquist:
Python 2.7 HTMLParse.py lines 185-199 (similar lines still exist in Python 3.4)
match = charref.match(rawdata, i)
if match:
...
else:
if ";" in rawdata[i:]: #bail by consuming &#
self.handle_data(rawdata[0:2])
i = self.updatepos(i, 2)
break
if you feed a broken charref, that is non-numeric, it will pass whatever random
string that happened to be at the start of rawdata to handle_data(). Eg:
p = HTMLParser()
p.handle_data = lambda x: sys.stdout.write(x)
p.feed('<p>&#foo;</p>')
will print '<p' which is clearly wrong. I think the intention of the code is to
pass '&#', which seems saner.
