Synopsis:	Moderate: tetex security update
Issue date:	2010-05-06
CVE Names:	CVE-2007-5935 CVE-2009-0791 CVE-2009-3609
 CVE-2010-0739 CVE-2010-0827 CVE-2010-1440

A buffer overflow flaw was found in the way teTeX processed virtual font
files 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-2010-0827)

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)

A stack-based buffer overflow flaw was found in the way teTeX processed
DVI files containing HyperTeX references with long titles, when
converting them into PostScript. An attacker could create a malicious
DVI file that would cause the dvips executable to crash. (CVE-2007-5935)

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. 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-2009-3609)
