Synopsis
The remote Scientific Linux host is missing one or more security updates.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)
All users of tetex are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
