Xpdf : Security Vulnerabilities, CVEs, Published In 2005 (Overflow)

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.

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.

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.

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.

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.

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.

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.

Buffer overflow in the Gfx::doImage function in Gfx.cc for xpdf 3.00, and other products that share code such as tetex-bin and kpdf in KDE 3.2.x to 3.2.3 and 3.3.x to 3.3.2, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted PDF file that causes the boundaries of a maskColors array to be exceeded.
