Description D'juan McDonald (domhnall) 2018-12-28 02:41:55 UTC 
(https://nvd.nist.gov/vuln/detail/CVE-2018-20481):

XRef::getEntry in XRef.cc in Poppler 0.72.0 mishandles unallocated XRef entries, which allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted PDF document, when XRefEntry::setFlag in XRef.h is called from Parser::makeStream in Parser.cc.

Patch: https://gitlab.freedesktop.org/adamreichold/poppler/commit/32a92c54f6df4e57f41e4f3ee03bbe5d6e066ef8

A reachable Object::getString assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to construction of invalid rich media annotation assets in the AnnotRichMedia class in Annot.c.
