<p>
libgtop facilitates the libgtop_daemon, which is used by GNOME to
obtain information about remote systems.

<description>
<p>
Liu Qishuai discovered that glibtop_get_proc_map_s() in
sysdeps/linux/procmap.c does not properly allocate memory for storing a
filename, allowing certain filenames to cause the buffer to overflow on
the stack.
</p>
</description>
<impact type="normal">
<p>
By tricking a victim into executing an application that uses the
libgtop library (e.g. libgtop_daemon or gnome-system-monitor), a local
attacker could specify a specially crafted filename to be used by
libgtop causing a buffer overflow and possibly execute arbitrary code
with the rights of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libgtop users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=gnome-base/libgtop-2.14.6&quot;</code>
</resolution>
