Vulnerabilidades

Multiple off-by-one errors in the (1) token and (2) linetoken functions in backend/dvi/mdvi-lib/afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a DVI file containing a crafted…

Heap-based buffer overflow in the linetoken function in afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a DVI file containing a crafted Adobe Font Metrics (AFM) file, a different…

Heap-based buffer overflow in the AFM font parser in the dvi-backend component in Evince 2.32 and earlier, teTeX 3.0, t1lib 5.1.2, and possibly other products allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font in conjunction with a DVI file…

Multiple integer overflows in dvipsk/dospecial.c in dvips in TeX Live 2009 and earlier, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a special command in a DVI file, related to the (1) predospecial and (2) bbdospecial functions, a different…

Multiple array index errors in set.c in dvipng 1.11 and 1.12, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed DVI file.

Integer overflow in dvips in TeX Live 2009 and earlier, and teTeX, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted virtual font (VF) file associated with a DVI file.

Integer overflow in the predospecial function in dospecial.c in dvips in (1) TeX Live and (2) teTeX might allow user-assisted remote attackers to execute arbitrary code via a crafted DVI file that triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.

dvips in teTeX and TeXlive 2007 and earlier allows local users to obtain sensitive information and modify certain data by creating certain temporary files before they are processed by dviljk, which can then be read or modified in place.

Stack-based buffer overflow in hpc.c in dvips in teTeX and TeXlive 2007 and earlier allows user-assisted attackers to execute arbitrary code via a DVI file with a long href tag.

Multiple buffer overflows in dvi2xx.c in dviljk in teTeX and TeXlive 2007 and earlier might allow user-assisted attackers to execute arbitrary code via a crafted DVI input file.

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 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.

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.

The xdvizilla script in tetex-bin 2.0.2 creates temporary files with predictable file names, which allows local users to overwrite arbitrary files via a symlink attack.

teTeX filter before 1.0.7 allows local users to gain privileges via a symlink attack on temporary files that are produced when printing .dvi files using lpr.
