Synopsis |
16 |
======== |
17 |
|
18 |
libgtop improperly handles filenames, possibly allowing for the |
19 |
execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
libgtop facilitates the libgtop_daemon, which is used by GNOME to |
25 |
obtain information about remote systems. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 gnome-base/libgtop < 2.14.6 >= 2.14.6 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
Liu Qishuai discovered that glibtop_get_proc_map_s() in |
39 |
sysdeps/linux/procmap.c does not properly allocate memory for storing a |
40 |
filename, allowing certain filenames to cause the buffer to overflow on |
41 |
the stack. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
By tricking a victim into executing an application that uses the |
47 |
libgtop library (e.g. libgtop_daemon or gnome-system-monitor), a local |
48 |
attacker could specify a specially crafted filename to be used by |
49 |
libgtop causing a buffer overflow and possibly execute arbitrary code |
50 |
with the rights of the user running the application. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All libgtop users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose ">=gnome-base/libgtop-2.14.6" |
64 |
