Synopsis |
16 |
======== |
17 |
|
18 |
A vulnerability in LinuxCIFS may allow a remote code execution via a |
19 |
command line option. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
The LinuxCIFS utils are a collection of tools for managing Linux CIFS |
25 |
Client Filesystems. |
26 |
|

Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 net-fs/cifs-utils < 6.11 >= 6.11 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
The mount.cifs utility had a shell injection issue where one can embed |
39 |
shell commands via the username mount option. Those commands will be |
40 |
run via popen() in the context of the user calling mount. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
A remote attacker could entice a user to use a specially crafted |
46 |
argument using mount.cifs, possibly resulting in execution of arbitrary |
47 |
code with the privileges of the process or a Denial of Service |
48 |
condition. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All LinuxCIFS users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=net-fs/cifs-utils-6.11" |
