news 28 Posted May 6, 2010 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: tetex security update Advisory ID: RHSA-2010:0400-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0400.html Issue date: 2010-05-06 CVE Names: CVE-2009-0146 CVE-2009-0147 CVE-2009-0166 CVE-2009-0195 CVE-2009-0791 CVE-2009-0799 CVE-2009-0800 CVE-2009-1179 CVE-2009-1180 CVE-2009-1181 CVE-2009-1182 CVE-2009-1183 CVE-2009-3608 CVE-2009-3609 CVE-2010-0739 CVE-2010-0829 CVE-2010-1440 ===================================================================== 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.
