"From Red Hat Security Advisory 2011:0309 :

Updated pango packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Pango is a library used for the layout and rendering of
internationalized text.

It was discovered that Pango did not check for memory reallocation
failures in the hb_buffer_ensure() function. An attacker able to
trigger a reallocation failure by passing sufficiently large input to
an application using Pango could use this flaw to crash the
application or, possibly, execute arbitrary code with the privileges
of the user running the application. (CVE-2011-0064)

Red Hat would like to thank the Mozilla Security Team for reporting
this issue.

All pango users should upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing
this update, you must restart your system or restart the X server for
the update to take effect."
