red hat
Calendar Grey July 21, 2011
Dist Redhat Esm H88
Enhance freetype installations on Red Hat Enterprise Linux to mitigate a severe security vulnerability impacting font display functionality.
Updated freetype packages that fix one security issue are now available for Red Hat Enterprise Linux 6

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

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. These packages provide the FreeType 2 font engine.
A flaw was found in the way the FreeType font rendering engine processed certain PostScript Type 1 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-2011-0226)
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.
