Synopsis

The remote CentOS 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 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.

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.

Solution

Update the affected tetex packages.
