=====================================================================
1. Summary:
Updated freetype packages that fix various security issues are now
available for Red Hat Enterprise Linux 2.1.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Description:
FreeType is a free, high-quality, portable font engine that can open and
manage font files. It also loads, hints, and renders individual glyphs
efficiently. These packages provide both the FreeType 1 and FreeType 2
font engines.
Tavis Ormandy of the Google Security Team discovered several integer
overflow flaws in the FreeType 2 font engine. If a user loaded a
carefully-crafted font file with an application linked against FreeType 2,
it could cause the application to crash or, possibly, execute arbitrary
code with the privileges of the user running the application.
(CVE-2009-0946)
Chris Evans discovered multiple integer overflow flaws in the FreeType font
engine. If a user loaded a carefully-crafted font file with an application
linked against FreeType, it could cause the application to crash or,
possibly, execute arbitrary code with the privileges of the user running
the application. (CVE-2006-1861)
An integer overflow flaw was found in the way the FreeType font engine
processed TrueType® Font (TTF) files. If a user loaded a carefully-crafted
font file with an application linked against FreeType, it could cause the
application to crash or, possibly, execute arbitrary code with the
privileges of the user running the application. (CVE-2007-2754)
Note: For the FreeType 2 font engine, the CVE-2006-1861 and CVE-2007-2754
flaws were addressed via RHSA-2006:0500 and RHSA-2007:0403 respectively.
This update provides corresponding updates for the FreeType 1 font engine,
included in the freetype packages distributed in Red Hat Enterprise Linux
2.1.
Users are advised to upgrade to these updated packages, which contain
backported patches to correct these issues. The X server must be restarted
(log out, then log back in) for this update to take effect.
