In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.(CVE-2018-20662)

Poppler 0.74.0 has a heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter function.(CVE-2019-9631)

PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary.(CVE-2019-9903)");
