Xpdf 4.04 will deadlock on a PDF object stream whose "Length" field is itself in another object stream.

An excessively large PDF page size (found in fuzz testing, unlikely in normal PDF files) can result in a divide-by-zero in Xpdf's text extraction code. This is related to CVE-2022-30524, but the problem here is caused by a very large page size, rather than by a very large character coordinate.

 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 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.

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.”

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.

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.

XPDF v4.04 was discovered to contain a stack overflow via the function FileStream::copy() at xpdf/Stream.cc:795.

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.

An issue was discovered in Xpdf 4.04. There is a crash in convertToType0 in fofi/FoFiType1C.cc, a different vulnerability than CVE-2022-38928.

An issue was discovered in Xpdf 4.04. There is a crash in gfseek(_IO_FILE*, long, int) in goo/gfile.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 4.04 is vulnerable to Null Pointer Dereference in FoFiType1C.cc:2393.

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

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

Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIG2Stream.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-2021-30860 (Apple CoreGraphics).

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 DCMAKE_CXX_COMPILER=afl-clang-fast++ option.
