teTeX is an implementation of TeX. TeX takes a text file and a set of formatting commands as input, and creates a typesetter-independent DeVice Independent (DVI) file as output. 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 validati ... Description truncated, for more information please check the Reference URL
