CVE-2018-20551
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.
Does this matter?
Lower severity and a low EPSS score (1.94%). Track it; it rarely justifies an emergency change on its own.
