Synopsis |
16 |
======== |
17 |
|
18 |
multipath-tools does not set correct permissions on the socket file, |
19 |
making it possible to send arbitrary commands to the multipath daemon |
20 |
for local users. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
multipath-tools are used to drive the Device Mapper multipathing |
26 |
driver. |

35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
multipath-tools uses world-writable permissions for the socket file |
40 |
(/var/run/multipathd.sock). |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
Local users could send arbitrary commands to the multipath daemon, |
46 |
causing cluster failures and data loss. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
chmod o-rwx /var/run/multipath.sock |
52 |
|
53 |
Resolution |
54 |
========== |
55 |
|
56 |
All multipath-tools users should upgrade to the latest version: |
57 |
|
58 |
# emerge --sync |
59 |
# emerge --ask --oneshot --verbose ">=sys-fs/multipath-tools-0.4.8-r1" |
