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. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 sys-fs/multipath-tools < 0.4.8-r1 >= 0.4.8-r1 |
| 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" |
