*** This bug is a security vulnerability ***

There are these bugs in libpoppler-glib8:

https://gitlab.freedesktop.org/poppler/poppler/issues/845
https://gitlab.freedesktop.org/poppler/poppler/issues/846

The first is about sharing cairo_font_face_t instances in multiple
threads which is not thread-safe. The second is about accessing global
linked list struct without proper synchronisation mechanism.

Due to these two bugs poppler+cairo cannot be used for rendering
multiple documents in multiple threads.

The second may be potentially security vulnerability for applications
that use poppler+cairo in multiple threads due to writes to potentially
uninitialised pointer.

I noticed that poppler source package contains a lot of patches from
ubuntu updates. Would be possible to add patch to this problem to ubuntu
(and also debian) updates?
