NVD Description

Note: Versions mentioned in the description apply only to the upstream typelib-1_0-Poppler-0_18 package and not the typelib-1_0-Poppler-0_18 package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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.
