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.
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 strncpy from FoFiType1::parse in fofi/FoFiType1.cc because it does not ensure the source string has a valid length before making a fixed-length copy. It can, for example, be triggered by sending a crafted PDF document to the pdftotext tool. It allows an attacker to use a crafted pdf file to cause Denial of Service or an information leak, or possibly have unspecified other impact.
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.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function Splash::scaleImageYuXu at Splash.cc for y Bresenham parameters.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function PostScriptFunction::exec at Function.cc for the psOpMod case.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function ImageStream::ImageStream at Stream.cc for nComps.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function Splash::scaleImageYuXu at Splash.cc for x Bresenham parameters.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function PSOutputDev::checkPageSlice at PSOutputDev.cc for nStripes.
An issue was discovered in Xpdf 4.01.01. There is an FPE in the function PostScriptFunction::exec at Function.cc for the psOpIdiv case.
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.
