1. Summary:

Updated tetex packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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 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. (CVE-2009-0799,
CVE-2009-1181, CVE-2009-1183)

Red Hat would like to thank Braden Thomas and Drew Yao of the Apple Product
Security team, Will Dormann of the CERT/CC, Alin Rad Pop of Secunia
Research, and Chris Rohlf, for responsibly reporting the Xpdf flaws.

All users of tetex are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
