| Descripción: | Summary:
The remote host is missing an update for the 'tetex'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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)
