Scientific Linux Security Update : t1lib 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 :

The t1lib library allows you to rasterize bitmaps from PostScript Type
1 fonts.

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 an application linked against t1lib, it could cause
the application to crash or, potentially, execute arbitrary code with
the privileges of the user running the application. (CVE-2010-2642,
CVE-2011-0433)

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

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

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

An out-of-bounds memory read flaw was found in t1lib. A
specially-crafted font file could, when opened, cause an application
linked against t1lib to crash. (CVE-2011-1552)

All users of t1lib are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. All
applications linked against t1lib must be restarted for this update to
take effect.
