Moderate: libgtop2 security update

An updated libgtop2 package that fixes a security issue and a functionality
bug is now available for Red Hat Enterprise Linux 4.

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

The libgtop2 package contains a library for obtaining information about a
running system, such as cpu, memory and disk usage; active processes; and
PIDs.

A flaw was found in the way libgtop2 handled long filenames mapped
into the address space of a process. An attacker could execute arbitrary
code on behalf of the user running gnome-system-monitor by executing a
process and mapping a file with a specially crafted name into the
processes' address space. (CVE-2007-0235)

This update also fixes the following bug:

* when a version of libgtop2 compiled to run on a 32-bit architecture was
used to inspect a process running in 64-bit mode, it failed to report
certain information regarding address space mapping correctly.

All users of gnome-system-monitor are advised to upgrade to this updated
libgtop2 package, which contains backported patches that resolve these issues.

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
