In xpdf, the xref table contains an infinite loop which allows remote attackers to cause a denial of service (application crash) in xpdf-based PDF viewers.
An issue was discovered in xpdf 4.00. An infinite loop in XRef::Xref allows an attacker to cause denial of service because loop detection exists only for tables, not streams.
xpdf 4.04 allocates excessive memory when presented with crafted input. This can be triggered by (for example) sending a crafted PDF document to the pdftoppm binary. It is most easily reproduced with the DCMAKE_CXX_COMPILER=afl-clang-fast++ option.
An issue was discovered in xpdf 4.00. A NULL pointer dereference in readCodestream allows an attacker to cause denial of service via a JPX image with zero components.
The JBIG2Stream::readGenericBitmap function in JBIG2Stream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
A NULL pointer dereference in JPXStream::fillReadBuf in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file, as demonstrated by pdftohtml.
A NULL pointer dereference in XFAForm::scanFields in XFAForm.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file, as demonstrated by pdftohtml.
An out-of-bounds read in JPXStream::readTilePart in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file, as demonstrated by pdftohtml.
The JPXStream::inverseTransformLevel function in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
The JBIG2MMRDecoder::getBlackCode function in JBIG2Stream.cc in xpdf 4.00 allows attackers to launch denial of service (buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
The BufStream::lookChar function in Stream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
A large loop in JBIG2Stream::readSymbolDictSeg in xpdf 4.00 allows an attacker to cause denial of service via a specific file due to inappropriate decoding.
The JPXStream::fillReadBuf function in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
The JPXStream::readTilePartData function in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
The JPXStream::close function in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer over-read and application crash) via a specific pdf file, as demonstrated by pdftohtml.
An issue was discovered in Xpdf 4.04. There is a crash in XRef::fetch(int, int, Object*, int) in xpdf/XRef.cc, a different vulnerability than CVE-2018-16369 and CVE-2019-16088.
A stack overflow in the Catalog::readPageLabelTree2(Object*) function of XPDF v4.04 allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.
Buffer Overflow vulnerability found in XPDF v.4.04 allows an attacker to cause a Denial of Service via the PDFDoc malloc in the pdftotext.cc function. NOTE: Vendor states “it's an expected abort on out-of-memory error.”
