Description

Updated newt packages that fix one security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Newt is a programming library for color text mode, widget-based user interfaces. Newt can be used to add stacked windows, entry widgets, checkboxes, radio buttons, labels, plain text fields, scrollbars, and so on, to text mode user interfaces.

A heap-based buffer overflow flaw was found in the way newt processes content that is to be displayed in a text dialog box. A local attacker could issue a specially crafted text dialog box display request (direct or via a custom application), leading to a denial of service (application crash) or, potentially, arbitrary code execution with the privileges of the user running the application using the newt library. (CVE-2009-2905)

Users of newt should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, all applications using the newt library must be restarted for the update to take effect.
