That looks quite similar to what I have received in #924050.
(Also the address offsets are the same.)
Therefore this issue should solvable by the patch attached to [1].
A poppler package built with that patch showed the
signature information successfully.
An upstream bug is also referenced there and information
how to reproduce.

Kind regards,
Bernhard
