CVE Names:	CVE-2009-0146 CVE-2009-0147 CVE-2009-0166
 CVE-2009-0195 CVE-2009-0791 CVE-2009-0799

 CVE-2010-0829 CVE-2010-1440

Multiple integer overflow flaws were found in the way teTeX processed
special commands when converting DVI files into PostScript. An attacker
could create a malicious DVI file that would cause the dvips executable
to crash or, potentially, execute arbitrary code. (CVE-2010-0739,
CVE-2010-1440)

Multiple array index errors were found in the way teTeX converted DVI
files into the Portable Network Graphics (PNG) format. An attacker could
create a malicious DVI file that would cause the dvipng executable to
crash. (CVE-2010-0829)

teTeX embeds a copy of Xpdf, an open source Portable Document Format
(PDF) file viewer, to allow adding images in PDF format to the generated
PDF documents. The following issues affect Xpdf code:

Multiple integer overflow flaws were found in Xpdf's JBIG2 decoder. If a
local user generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash or,
potentially, execute arbitrary code with the privileges of the user
running pdflatex. (CVE-2009-0147, CVE-2009-1179)

Multiple integer overflow flaws were found in Xpdf. If a local user
generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash or,
potentially, execute arbitrary code with the privileges of the user
running pdflatex. (CVE-2009-0791,
CVE-2009-3608, CVE-2009-3609)

A heap-based buffer overflow flaw was found in Xpdf's JBIG2 decoder. If
a local user generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash or,
potentially, execute arbitrary code with the privileges of the user
running pdflatex. (CVE-2009-0195)

Multiple buffer overflow flaws were found in Xpdf's JBIG2 decoder. If a
local user generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash or,
potentially, execute arbitrary code with the privileges of the user
running pdflatex. (CVE-2009-0146, CVE-2009-1182)

Multiple flaws were found in Xpdf's JBIG2 decoder that could lead to the
freeing of arbitrary memory. If a local user generated a PDF file from a
TeX document, referencing a specially-crafted PDF file, it would cause
Xpdf to crash or, potentially, execute arbitrary code with the
privileges of the user running pdflatex. (CVE-2009-0166, CVE-2009-1180)

Multiple input validation flaws were found in Xpdf's JBIG2 decoder. If a
local user generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash or,
potentially, execute arbitrary code with the privileges of the user
running pdflatex. (CVE-2009-0800)

Multiple denial of service flaws were found in Xpdf's JBIG2 decoder. If
a local user generated a PDF file from a TeX document, referencing a
specially-crafted PDF file, it would cause Xpdf to crash.
