1.169.1.  RHSA-2009:0476: Important security update


This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:0476
Updated pango and evolution28-pango packages that fix an integer overflow flaw are now available for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having important security impact by the Red Hat Security Response Team.
Pango is a library used for the layout and rendering of internationalized text.
Will Drewry discovered an integer overflow flaw in Pango's pango_glyph_string_set_size() function. If an attacker is able to pass an arbitrarily long string to Pango, it may be possible to execute arbitrary code with the permissions of the application calling Pango. (CVE-2009-1194)
pango and evolution28-pango users 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. Note: Restarting the X server closes all open applications and logs you out of your session.

1.169.2.  RHBA-2009:1395: bug fix update

An updated Pango package that rectifies a dependency issue is now available.
Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+.
Pango is designed to be modular; the core Pango layout engine can be used with different font back-ends.
The integration of Pango with Cairo provides a complete solution with high quality text handling and graphics rendering.
This update addresses the following bug:
  • it was possible to install Pango (and applications that relied upon Pango), without having any fonts installed. This would prevent applications from loading (as they could not render text) and resulted in an error message. Changes have been made to ensure that the bitsream-vera-fonts package is now a dependency of Pango. With the font present, applications reliant upon Pango can load and render text correctly. (BZ#251928)
User should upgrade to the updated package, which resolves this issue.
