Vulnerabilidades

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 4.04 lacked an integer overflow check in JPXStream.cc.

In Xpdf prior to 4.04, the DCT (JPEG) decoder was incorrectly allowing the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc.

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…

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

There is a Null Pointer Dereference vulnerability in the XFAScanner::scanNode() function in XFAScanner.cc in xpdf 4.03.

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.

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 Denial of Service…

xpdf 4.03 has heap buffer overflow in the function readXRefTable located in XRef.cc. An attacker can exploit this bug to cause a Denial of Service (Segmentation fault) or other unspecified effects by sending a crafted PDF file to the pdftoppm binary.

An integer overflow was addressed with improved input validation. This issue is fixed in Security Update 2021-005 Catalina, iOS 14.8 and iPadOS 14.8, macOS Big Sur 11.6, watchOS 7.6.2. Processing a maliciously crafted PDF may lead to arbitrary code execution. Apple is aware of a report that this issue may have been…

Xpdf 4.02 allows stack consumption because of an incorrect subroutine reference in a Type 1C font charstring, related to the FoFiType1C::getOp() function.

In Xpdf 4.02, SplashOutputDev::endType3Char(GfxState *state) SplashOutputDev.cc:3079 is trying to use the freed `t3GlyphStack->cache`, which causes an `heap-use-after-free` problem. The codes of a previous fix for nested Type 3 characters wasn't correctly handling the case where a Type 3 char referred to another char…

There is an invalid memory access in the function fprintf located in Error.cc in Xpdf 4.0.2. It can be triggered by sending a crafted PDF file to the pdftohtml binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.

There is an invalid memory access in the function TextString::~TextString() located in Catalog.cc in Xpdf 4.0.2. It can be triggered by (for example) sending a crafted pdf file to the pdftohtml binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other…

The error function in Error.cc in poppler before 0.21.4 allows remote attackers to execute arbitrary commands via a PDF containing an escape sequence for a terminal emulator.

In xpdf, the xref table contains an infinite loop which allows remote attackers to cause a denial of service (application crash) in xpdf-based PDF viewers.

xpdf allows remote attackers to cause a denial of service (NULL pointer dereference and crash) in the way it processes JBIG2 PDF stream objects.

Catalog.cc in Xpdf 4.02 has a NULL pointer dereference because Catalog.pageLabels is initialized too late in the Catalog constructor.

In Xpdf 4.01.01, a stack-based buffer under-read could be triggered in IdentityFunction::transform in Function.cc, used by GfxAxialShading::getColor. It can, for example, be triggered by sending a crafted PDF document to the pdftoppm tool. It allows an attacker to use a crafted PDF file to cause Denial of Service or…

Xpdf 3.04 has a SIGSEGV in XRef::fetch in XRef.cc after many recursive calls to Catalog::countPageTree in Catalog.cc.

Xpdf 2.00 allows a SIGSEGV in XRef::constructXRef in XRef.cc. NOTE: 2.00 is a version from November 2002.
