[New-bugs-announce] [issue1003] zipfile password fails validation

[David W]

New submission from David W:

This is in python2.5: zipfile.py SVN rev-56308
When testing a zipfile.Zipfile().read() with a password protected zip
file, I would continually get exceptions.  So I tracked this down to 
line 796-797: 
if ord(h[11]) != ((zinfo.CRC>>24)&255):
        raise RuntimeError, "Bad password for file %s" % name

scope related data:
bytes = `)¶G\x02ùû¬&\x1E#çÕ`
h[11] = `¯`
zinfo.CRC = `1554440319`

ord(h[11]) == 175
((zinfo.CRC>>24)&255) == 92


When I commented out the error check, the script extracted 150 JPGs with
no corruption or errors in any of the images...so its just seems like an
issue with the error check.
