Red Hat Security Advisory 2011-1325-01 - Pango is a library used for the layout and rendering of internationalized text. A buffer overflow flaw was found in HarfBuzz, an OpenType text shaping engine used in Pango. If a user loaded a specially-crafted font file with an application that uses Pango, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. Users of evolution28-pango are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, you must restart your system or restart the X server for the update to take effect.
