New submission from Jakub Wilk:
The MO file format specification[0] reads:
"A program seeing an unexpected major revision number should stop reading the
MO file entirely"
But Python doesn't pay attention to versions at all.
As a test-case I attached a MO file with a bogus major revision number.
msgunfmt correcly rejects such a file:
$ msgunfmt messages.mo
msgunfmt: file "messages.mo" is not in GNU .mo format
Yet Python opens it happily:
>>> import gettext
>>> t = gettext.GNUTranslations(open("messages.mo", "rb"))
>>> t.gettext("foo")
'bar'
