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>

|
<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 ">=gnome-base/libgtop-2.14.6"</code>
