A floating-point exception in the PSStack::roll function of Poppler before 25.04.0 can cause an application to crash when handling malformed inputs associated with INTMIN.

An issue was discovered in Poppler 22.07.0. There is a reachable abort which leads to denial of service because the main function in pdfunite.cc lacks a stream check before saving an embedded file.

A reachable Object::getString assertion in Poppler 22.07.0 allows attackers to cause a denial of service due to a failure in markObject.

An issue was discovered in Poppler 22.08.0. There is a reachable assertion in Object.h, will lead to denial of service because PDFDoc::replacePageDict in PDFDoc.cc lacks a stream check before saving an embedded file.

Buffer Overflow vulnerability in HtmlOutputDev::page in poppler 0.75.0 allows attackers to cause a denial of service.

Uncontrolled Recursion in pdfinfo, and pdftops in poppler 0.89.0 allows remote attackers to cause a denial of service via crafted input.

In Poppler 22.07.0, PDFDoc::savePageAs in PDFDoc.c callows attackers to cause a denial-of-service (application crashes with SIGABRT) by crafting a PDF file in which the xref data structure is mishandled in getCatalog processing. Note that this vulnerability is caused by the incomplete patch of CVE-2018-20662.

An issue was discovered in freedesktop poppler version 20.12.1, allows remote attackers to cause a denial of service (DoS) via crafted .pdf file to FoFiType1C::convertToType1 function.

An issue was discovered in freedesktop poppler version 20.12.1, allows remote attackers to cause a denial of service (DoS) via crafted .pdf file to FoFiType1C::cvtGlyph function.

A vulnerability in Outline.cc for Poppler prior to 23.06.0 allows a remote attacker to cause a Denial of Service (DoS) (crash) via a crafted PDF file in OutlineItem::open.

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 logic error in the Hints::Hints function of Poppler v22.03.0 allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.

DISPUTED DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects.

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.

A vulnerability was found in Poppler before 0.76.0 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.

FontInfoScanner::scanFonts in FontInfo.cc in Poppler 0.75.0 has infinite recursion, leading to a call to the error function in Error.cc.

An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function PSOutputDev::checkPageSlice at PSOutputDev.cc.

An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function PSOutputDev::checkPageSlice at PSOutputDev.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 downsamplerowboxfilter function.

An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readGenericBitmap() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfseparate binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JArithmeticDecoder::decodeBit.

An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readTextRegion() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JBIG2Bitmap::clearToZero.

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.

A flaw was found in Poppler 0.72.0. The PDFDoc::setup class 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 flaw was found in Poppler 0.72.0. A NULL pointer dereference in the XRef::getEntry class in XRef.cc file due to the mishandle of unallocated XRef entries. This allows remote attackers to cause a denial of service via a crafted PDF document, when XRefEntry::setFlag in XRef.h is called from Parser::makeStream in Parser.cc.
