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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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.

4. Solution:

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