"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.

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(r) 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."
