[issue11443] Zip password issue

[Yaroslav]

New submission from Yaroslav <sbojchuk at gmail.com>:

There's issue while setting password.
I brute-force different passwords for that arhive-file, and it pass with different, not correct password. For that arhive password is: "pass", but that arhive is correct in python and even extract files from that with not correct passwords:
('Password is:', 'aafy')
('Password is:', 'aakv')
('Password is:', 'aavu')
('Password is:', 'aazs')
('Password is:', 'abgj')
('Password is:', 'abmr')
('Password is:', 'abzo')
('Password is:', 'acds')
('Password is:', 'acdu')
('Password is:', 'ace')
('Password is:', 'achc')
('Password is:', 'acue')
('Password is:', 'acxi')
('Password is:', 'adcj')
('Password is:', 'adcl')
('Password is:', 'adde')
('Password is:', 'advx')
('Password is:', 'aenu')
('Password is:', 'afbl')
('Password is:', 'afqg')
('Password is:', 'afyl')
('Password is:', 'agef')
('Password is:', 'agtv')
('Password is:', 'aimo')
('Password is:', 'aizr')
('Password is:', 'ajjt')
('Password is:', 'ajlj')
('Password is:', 'akqr')
...
Of course content of file is not correct ("Q1E85�ڳM��ژo��
H*]	5Q���
                             
��
��X">_+x�����
��I�k�~L>��
").

z = zipfile.ZipFile("data.zip", 'r')
z.setpassword("aafy")
print(z.read("secretfile.txt"))
