CVE-2018-16646
In Poppler 0.68.0, the Parser::getObj() function in Parser.cc may cause infinite recursion via a crafted file. A remote attacker can leverage this for a DoS attack.
CVE-2018-18897
An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo.
CVE-2018-19058
An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file.
CVE-2018-19059
An issue was discovered in Poppler 0.71.0. There is a out-of-bounds read in EmbFile::save2 in FileSpec.cc, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating embedded files before save attempts.
CVE-2018-19060
An issue was discovered in Poppler 0.71.0. There is a NULL pointer dereference in goo/GooString.h, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating a filename of an embedded file before constructing a save path.
CVE-2018-19149
Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from poppler_annot_file_attachment_get_attachment.
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.
CVE-2018-20650
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.
CVE-2018-20662
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-2019-7310
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo.
CVE-2019-9200

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