Scientific Linux Security Update : texlive on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

TeX Live 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. The texlive packages provide
a number of utilities, including dvips.

TeX Live embeds a copy of t1lib. The t1lib library allows you 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 a TeX Live utility, it could cause the utility to
crash or, potentially, execute arbitrary code with the privileges of
the user running the utility. (CVE-2010-2642, CVE-2011-0433)

An invalid pointer dereference flaw was found in t1lib. A
specially-crafted font file could, when opened, cause a TeX Live
utility to crash or, potentially, execute arbitrary code with the
privileges of the user running the utility. (CVE-2011-0764)

A use-after-free flaw was found in t1lib. A specially-crafted font
file could, when opened, cause a TeX Live utility to crash or,
potentially, execute arbitrary code with the privileges of the user
running the utility. (CVE-2011-1553)

An off-by-one flaw was found in t1lib. A specially-crafted font file
could, when opened, cause a TeX Live utility to crash or, potentially,
execute arbitrary code with the privileges of the user running the
utility. (CVE-2011-1554)

An out-of-bounds memory read flaw was found in t1lib. A
specially-crafted font file could, when opened, cause a TeX Live
utility to crash. (CVE-2011-1552)

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