Dist Redhat Esm H88
Newly released freetype updates have been issued to address a critical vulnerability in Red Hat Enterprise Linux versions 5 and 6.
Updated freetype packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

Summary

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.
