3. Description:
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.
4. 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
5. Bugs fixed (http://bugzilla.redhat.com/):
