In Xpdf 4.05 (and earlier), invalid header info in a DCT (JPEG) stream can lead to an uninitialized variable in the DCT decoder. The proof-of-concept PDF file causes a segfault attempting to read from an invalid address.

In Xpdf 4.05 (and earlier), very large coordinates in a page box can cause an integer overflow and divide-by-zero.

In Xpdf 4.05 (and earlier), a PDF object loop in a pattern resource leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, due to missing object type check in AcroForm field reference.

In Xpdf 4.05 (and earlier), a PDF object loop in the PDF resources leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by an invalid character code in a Type 1 font. The root problem was a bounds check that was being optimized away by modern compilers.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by long Unicode sequence in ActualText.

In Xpdf 4.05 (and earlier), a PDF object loop in the attachments leads to infinite recursion and a stack overflow.

In Xpdf 4.05 (and earlier), a PDF object loop in an object stream leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by negative object number in indirect reference in the input PDF file.

An infinite recursion in Catalog::findDestInTree can cause denial of service for xpdf 4.02.

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.

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.”

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.

Buffer Overflow vulnerability in pdfimages in xpdf 4.03 allows attackers to crash the application via crafted command.

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 gfseek(IOFILE, long, int) in goo/gfile.cc.

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 XRef::fetch(int, int, Object, int) in xpdf/XRef.cc, a different vulnerability than CVE-2018-16369 and CVE-2019-16088.

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).

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.
