Synopsis
The remote Red Hat host is missing one or more security updates.
Description
Updated tetex packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3.
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.
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.
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)
All users of tetex are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
Solution
Update the affected packages.
