"Updated freetype packages that fix one security issue are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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.

A flaw was found in the way the FreeType font rendering engine
processed certain Glyph Bitmap Distribution Format (BDF) fonts. If a
user loaded a specially 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-2012-5669)

Users are advised to upgrade to these updated packages, which contain
a backported patch to correct this issue. The X server must be
restarted (log out, then log back in) for this update to take effect."
