In Xpdf 4.04 (and earlier), a PDF object loop in the page label tree leads to infinite recursion and a stack overflow.

XPDF v4.04 was discovered to contain a stack overflow vulnerability via the Object::Copy class of object.cc files.

There is a use-after-free issue in JBIG2Stream::close() located in JBIG2Stream.cc in Xpdf 4.04. It can be triggered by sending a crafted PDF file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service or possibly have unspecified other impact.

XPDF 4.04 is vulnerable to Null Pointer Dereference in FoFiType1C.cc:2393.

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 DCMAKECXXCOMPILER=afl-clang-fast++ option.

XPDF v4.0.4 was discovered to contain a segmentation violation via the component /xpdf/AcroForm.cc:538.

XPDF v4.04 and earlier was discovered to contain a stack overflow via the function Catalog::countPageTree() at Catalog.cc.

Stack overflow vulnerability in function gmalloc in goo/gmem.cc in xpdf 4.04, allows local attackers to cause a denial of service.

Stack overflow vulnerability in function Dict::find in xpdf/Dict.cc in xpdf 4.04, allows local attackers to cause a denial of service.

DISPUTED 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.”

In Xpdf 4.04 (and earlier), a PDF object loop in the embedded file tree leads to infinite recursion and a stack overflow.

In Xpdf 4.04 (and earlier), a bad color space object in the input PDF file can cause a divide-by-zero.
