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.

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."

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.

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.

Multiple integer overflows in xpdf 2.0 and 3.0, and other packages that use xpdf code such as CUPS, gpdf, and kdegraphics, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0889.

Multiple integer overflows in xpdf 3.0, and other packages that use xpdf code such as CUPS, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0888.
