From Red Hat Security Advisory 2010:0400 :

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.

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.

Specially crafted dvi files could cause buffer overflows in dvips and dvipng (CVE-2010-0827 / CVE-2010-0829 / CVE-2010-0739 / CVE-2010-1440). This has been fixed.

Upgrades dvipng to version 1.13 which fixes CVE-2010-0829.

Dan Rosenberg discovered that in dvipng, a utility that converts DVI files to PNG graphics, several array index errors allow context-dependent attackers, via a specially crafted DVI file, to cause a denial of service (crash of the application), and possibly arbitrary code execution.

Specially crafted dvi files could cause buffer overflows in dvips and dvipng (CVE-2010-0827, CVE-2010-0829, CVE-2010-0739, CVE-2010-1440).

Multiple vulnerabilities has been discovered and fixed in tetex :

Buffer overflow in BibTeX 0.99 allows context-dependent attackers to cause a denial of service (memory corruption and crash) via a long .bib bibliography file (CVE-2009-1284).

Integer overflow in the ObjectStream::ObjectStream function in XRef.cc in Xpdf 3.x before 3.02pl4 and Poppler before 0.12.1, as used in GPdf, kdegraphics KPDF, CUPS pdftops, and teTeX, might allow remote attackers to execute arbitrary code via a crafted PDF document that triggers a heap-based buffer overflow (CVE-2009-3608).

Integer overflow in dvips in TeX Live 2009 and earlier, and teTeX, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted virtual font (VF) file associated with a DVI file (CVE-2010-0827).

Multiple array index errors in set.c in dvipng 1.11 and 1.12, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed DVI file (CVE-2010-0829).

Integer overflow in the predospecial function in dospecial.c in dvips in (1) TeX Live and (2) teTeX might allow user-assisted remote attackers to execute arbitrary code via a crafted DVI file that triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third-party information (CVE-2010-0739).

Multiple integer overflows in dvipsk/dospecial.c in dvips in TeX Live 2009 and earlier, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a special command in a DVI file, related to the (1) predospecial and (2) bbdospecial functions, a different vulnerability than CVE-2010-0739 (CVE-2010-1440).

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

The corrected packages solves these problems.

Dan Rosenberg discovered that dvipng incorrectly handled certain malformed dvi files. If a user or automated system were tricked into processing a specially crafted dvi file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.
