RHSA-2009:0476 - Important: pango security update

Synopsis

Important: pango security update

Type/Severity

Security Advisory Important

Topic

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.

Description

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.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
