Advisory Release Date: 2019-08-23 17:01 Pacific
Advisory Updated Date: 2019-08-26 22:23 Pacific
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-2018-20481)
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-2018-16646)
Poppler 0.74.0 has a heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter function.(CVE-2019-9631)
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-2018-20650)
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-2018-19059)
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-2018-19058)
Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from poppler_annot_file_attachment_get_attachment.(CVE-2018-19149)
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-2019-7310)
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-2018-18897)
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-2018-19060)
A heap-based buffer underwrite exists in ImageStream::getLine() located at Stream.cc in Poppler 0.74.0 that can (for example) be triggered by sending a crafted PDF file to the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.(CVE-2019-9200)
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)
