Description

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. (CVE-2011-3193)

Users of 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.
