available for Red Hat Enterprise Linux 5.6 Extended Update Support.

The Red Hat Security Response Team has rated this update as having

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.

Multiple input validation flaws were found in the way FreeType
processed bitmap font files. If a specially crafted font file was
loaded by an application linked against FreeType, it could cause the
application to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2011-3256)

Multiple input validation flaws were found in the way FreeType
processed CID-keyed fonts. If a specially crafted font file was loaded
by an application linked against FreeType, it could cause the
application to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2011-3439)

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.
