Xpdf Security Vulnerabilities

CVE-2022-30524

There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denia...

CVE-2022-30775

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.

CVE-2022-33108

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

CVE-2022-36561

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

CVE-2022-38171

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-2...

CVE-2022-38222

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.

CVE-2022-38334

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

CVE-2022-38928

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

CVE-2022-41842

An issue was discovered in Xpdf 4.04. There is a crash in gfseek(_IO_FILE*, long, int) in goo/gfile.cc.

CVE-2022-41843

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.

CVE-2022-41844

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.

CVE-2022-43071

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.

CVE-2022-43295

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

CVE-2022-45586

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

CVE-2022-45587

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

CVE-2022-48545

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

CVE-2023-2662

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

CVE-2023-2663

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

CVE-2023-2664

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

CVE-2023-26930

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.”

CVE-2023-3044

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.

CVE-2023-3436

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

CVE-2024-7866

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

CVE-2024-7867

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

CVE-2024-7868

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.
