NVD Description

Note: Versions mentioned in the description apply only to the upstream poppler-demos package and not the poppler-demos package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in FileSpec.cc) in pdfdetach.
