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.
teTeX embeds a copy of t1lib to rasterize bitmaps from PostScript Type 1
fonts. The following issues affect t1lib code:
Two heap-based buffer overflow flaws were found in the way t1lib processed
Adobe Font Metrics (AFM) files. If a specially-crafted font file was opened
by teTeX, it could cause teTeX to crash or, potentially, execute arbitrary
code with the privileges of the user running teTeX. (CVE-2010-2642,
CVE-2011-0433)
An invalid pointer dereference flaw was found in t1lib. A specially-crafted
font file could, when opened, cause teTeX to crash or, potentially, execute
arbitrary code with the privileges of the user running teTeX.
(CVE-2011-0764)
A use-after-free flaw was found in t1lib. A specially-crafted font file
could, when opened, cause teTeX to crash or, potentially, execute arbitrary
code with the privileges of the user running teTeX. (CVE-2011-1553)
An off-by-one flaw was found in t1lib. A specially-crafted font file could,
when opened, cause teTeX to crash or, potentially, execute arbitrary code
with the privileges of the user running teTeX. (CVE-2011-1554)
An out-of-bounds memory read flaw was found in t1lib. A specially-crafted
font file could, when opened, cause teTeX to crash. (CVE-2011-1552)
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:
An uninitialized pointer use flaw was discovered in Xpdf. If pdflatex was
used to process a TeX document referencing a specially-crafted PDF file, it
could cause pdflatex to crash or, potentially, execute arbitrary code with
the privileges of the user running pdflatex. (CVE-2010-3702)
An array index error was found in the way Xpdf parsed PostScript Type 1
fonts embedded in PDF documents. If pdflatex was used to process a TeX
document referencing a specially-crafted PDF file, it could cause pdflatex
to crash or, potentially, execute arbitrary code with the privileges of the
user running pdflatex. (CVE-2010-3704)
Red Hat would like to thank the Evince development team for reporting
CVE-2010-2642. Upstream acknowledges Jon Larimer of IBM X-Force as the
original reporter of CVE-2010-2642.
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
use the Red Hat Network to apply this update are available at

5. Bugs fixed (http://bugzilla.redhat.com/):
595245 - CVE-2010-3702 xpdf: uninitialized Gfx::parser pointer dereference
638960 - CVE-2010-3704 xpdf: array indexing error in FoFiType1::parse()
666318 - CVE-2010-2642 evince, t1lib: Heap based buffer overflow in DVI file AFM font parser
679732 - CVE-2011-0433 evince, t1lib: Heap-based buffer overflow DVI file AFM font parser
692853 - CVE-2011-1552 t1lib: invalid read crash via crafted Type 1 font
692854 - CVE-2011-1553 t1lib: Use-after-free via crafted Type 1 font
