Description |
35 |
=========== |
36 |
|
37 |
It was discovered that Gentoo’s Asterisk ebuild does not properly set |
38 |
permissions on its data directories. This only affects OpenRC systems, |
39 |
as the flaw was exploitable via the init script. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
A local attacker could escalate privileges. |
45 |
|
46 |
Workaround |
47 |
========== |
48 |
|
49 |
Users should ensure the proper permissions are set as discussed in the |
50 |
referenced bugs. Do not run /etc/init.d/asterisk checkperms. |
51 |
|
52 |
Resolution |
53 |
========== |
54 |
|
55 |
All Asterisk users should upgrade to the latest version: |
56 |
|
57 |
# emerge --sync |
58 |
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-13.32.0-r1" |
