| Descripción: | Summary:
The remote host is missing an update for the 'tetex'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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)
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
