Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIGStream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2022-38171 in Xpdf.
A flaw was found in Poppler in the way certain PDF files were converted into HTML. A remote attacker could exploit this flaw by providing a malicious PDF file that, when processed by the 'pdftohtml' program, would crash the application causing a denial of service.
Poppler before 0.66.0 has an integer overflow in Parser::makeStream in Parser.cc.
An issue was discovered in Poppler through 0.78.0. There is a divide-by-zero error in the function SplashOutputDev::tilingPatternFill at SplashOutputDev.cc.
The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.
In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in FoFiType1C::convertToType0 in fofi/FoFiType1C.cc when it is trying to access the second privateDicts array element, because the privateDicts array has only one element allocated.
In Poppler through 0.76.1, there is a heap-based buffer over-read in JPXStream::init in JPEG2000Stream.cc via data with inconsistent heights or widths.
An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function Splash::blitTransparent at splash/Splash.cc.
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.
Poppler 0.74.0 has a heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter function.
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.
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.
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.
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.
A reachable Object::getString assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to construction of invalid rich media annotation assets in the AnnotRichMedia class in Annot.c.
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.
Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from poppler_annot_file_attachment_get_attachment.
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.
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.
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.
