libgtop2 security update

CentOS Errata and Security Advisory CESA-2007:0765

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.
