Terry J. Reedy added the comment:
The bug was not noticing the length mismatch caused by a corrupt zip file. It
is already fixed. The last link in your message opens
https://hg.python.org/cpython/file/2.7/Lib/zipfile.py#l238. A few lines
further, the code now has an added guard.
recData = data[start:start+sizeEndCentDir]
if len(recData) != sizeEndCentDir:
# Zip file is corrupted.
return None
endrec = list(struct.unpack(structEndArchive, recData))
When reporting a bug, please test on the currect release (ie, 2.7.11). If this
is not possible, and you have the specific traceback as here, one could look at
the current code online. Go to hg.python.org/cpython, select version in the
sidebar, select 'Browse' in the sidebar, and then, in this case, /Lib and
zipfile.py.
