Synopsis |
16 |
======== |
17 |
|
18 |
A vulnerability in NTFS-3G allows local users to gain root privileges. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
NTFS-3G is a stable, full-featured, read-write NTFS driver for various |
24 |
operating systems. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|
29 |
------------------------------------------------------------------- |
30 |
Package / Vulnerable / Unaffected |
31 |
------------------------------------------------------------------- |
32 |
1 sys-fs/ntfs3g < 2016.2.22-r2 >= 2016.2.22-r2 |
33 |
|
34 |
Description |
35 |
=========== |
36 |
|
37 |
The NTFS-3G driver does not properly clear environment variables before |
38 |
invoking mount or umount. |
39 |
|
40 |
This flaw is similar to the vulnerability described in "GLSA-201701-19" |
41 |
and "GLSA-201603-04" referenced below but is now implemented in the |
42 |
NTFS-3G driver itself. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
A local user could gain root privileges. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. However, on Gentoo when the |
53 |
"suid" USE flag is not set (which is the default) an attacker cannot |
54 |
exploit the flaw. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All NTFS-3G users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=sys-fs/ntfs3g-2016.2.22-r2" |
63 |
