"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)

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