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

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.

In Xpdf 4.04 (and earlier), a PDF object loop in the page label 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.

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

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

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

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

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.

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.”
