Check the top-level /Pages dictionary when finding the trailer in XRef.indexObjects (issue 12402)
#12662
Conversation
…ef.indexObjects` (issue 12402) In addition to the existing /Root and /Pages validation, also check that the /Pages-entry actually is a dictionary and that it has a valid /Count-entry. This way we can avoid picking a trailer candidate which e.g. the `Catalog.numPages` getter will just end up rejecting, thus breaking PDF document loading completely.
