[New-bugs-announce] [issue26038] zipfile cannot handle zip files where the archive size for a file does not match actual contents

[Brett Rosen]

New submission from Brett Rosen:

In python 2.7 it was able to handle this. It looks like this was introduced in https://github.com/python/cpython/commit/ae489fa76bb02daa636afe3bebec232e5aa9fac5 .

I'm not really sure if this should be considered a regression or not since the zip files that trigger this could be considered bad, even though unzip and older versions of zipfile.py could handle them.

I've attached a copy of a local diff I applied that worked around this issue, but I don't think it is a proper fix.
