Infinite loop in Xpdf due to missing validation in JPEG 2000 decoder

Infinite loop in Xpdf 4.06 and earlier, due to incorrect validation of progression order field in JPEG 2000 image.

Divide-by-zero in Xpdf 4.06 due to zero-height Type 3 glyph

Divide-by-zero in Xpdf 4.06 (and earlier), when a glyph in a Type 3 font has a zero height.

DCTStream:: reset()

Integer overflow in the DCTStream::reset method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a crafted PDF file, resulting in a heap-based buffer overflow.

The Adobe PDF specification 1.3, as implemented by (a) xpdf 3.0.1 patch 2, (b) kpdf in KDE before 3.5.5, (c) poppler before 0.5.4, and other products, allows remote attackers to have an unknown impact, possibly including denial of service (infinite loop), arbitrary code execution, or memory corruption, via a PDF file with a (1) crafted catalog dictionary or (2) a crafted Pages attribute that references an invalid page tree node.

xpdf: buffer overflow in FoFiType1::parse

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allows context-dependent attackers to execute arbitrary code via a PDF file with a crafted Type 1 font that can produce a negative value, leading to a signed-to-unsigned integer conversion error and a buffer overflow.

CCITTFaxStream:: lookChar()

Heap-based buffer overflow in the CCITTFaxStream::lookChar method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a PDF file that contains a crafted CCITTFaxDecode filter.

DCTStream:: readProgressiveDataUnit()

Array index error in the DCTStream::readProgressiveDataUnit method in xpdf/Stream.cc in Xpdf 3.02pl1, as used in poppler, teTeX, KDE, KOffice, CUPS, and other products, allows remote attackers to trigger memory corruption and execute arbitrary code via a crafted PDF file.

security flaw

Buffer overflow in the Decrypt::makeFileKey2 function in Decrypt.cc for xpdf 3.00 and earlier allows remote attackers to execute arbitrary code via a PDF file with a large /Encrypt /Length keyLength value.

security flaw

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

security flaw

xpdf and kpdf do not properly validate the "loca" table in PDF files, which allows local users to cause a denial of service (disk consumption and hang) via a PDF file with a "broken" loca table, which causes a large temporary file to be created when xpdf attempts to reconstruct the information.

security flaw

Multiple heap-based buffer overflows in the (1) DCTStream::readProgressiveSOF and (2) DCTStream::readBaselineSOF functions in the DCT stream parsing code (Stream.cc) in xpdf 3.01 and earlier, as used in products such as (a) Poppler, (b) teTeX, (c) KDE kpdf, (d) pdftohtml, (e) KOffice KWord, (f) CUPS, and (g) libextractor allow user-assisted attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with an out-of-range number of components (numComps), which is used as an array index.

security flaw

Heap-based buffer overflow in the StreamPredictor function in Xpdf 3.01, as used in products such as (1) Poppler, (2) teTeX, (3) KDE kpdf, and (4) pdftohtml, (5) KOffice KWord, (6) CUPS, and (7) libextractor allows remote attackers to execute arbitrary code via a PDF file with an out-of-range numComps (number of components) field.

security flaw

Heap-based buffer overflow in the JPXStream::readCodestream function in the JPX stream parsing code (JPXStream.c) for xpdf 3.01 and earlier, as used in products such as (1) Poppler, (2) teTeX, (3) KDE kpdf, (4) CUPS, and (5) libextractor allows user-assisted attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with large size values that cause insufficient memory to be allocated.

security flaw

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.

security flaw

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

security flaw

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

security flaw

Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via a DCTDecode stream with (1) a large "number of components" value that is not checked by DCTStream::readBaselineSOF or DCTStream::readProgressiveSOF, (2) a large "Huffman table index" value that is not checked by DCTStream::readHuffmanTables, and (3) certain uses of the scanInfo.numComps value by DCTStream::readScanInfo.

security flaw

Buffer overflow in the JBIG2Bitmap::JBIG2Bitmap function in JBIG2Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via unknown attack vectors.

security flaw

Heap-based buffer overflow in Splash.cc in xpdf, as used in other products such as (1) poppler, (2) kdegraphics, (3) gpdf, (4) pdfkit.framework, and others, allows attackers to cause a denial of service and possibly execute arbitrary code via crafted splash images that produce certain values that exceed the width or height of the associated bitmap.

security flaw

Certain patches for kpdf do not include all relevant patches from xpdf that were associated with CVE-2005-3627, which allows context-dependent attackers to exploit vulnerabilities that were present in CVE-2005-3627.
