Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in sudo may allow for privilege escalation. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
sudo allows a system administrator to give users the ability to run |
| 24 |
commands as other users. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-admin/sudo < 1.7.0 >= 1.7.0 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Harald Koenig discovered that sudo incorrectly handles group |
| 38 |
specifications in Runas_Alias (and related) entries when a group is |
| 39 |
specified in the list (using %group syntax, to allow a user to run |
| 40 |
commands as any member of that group) and the user is already a member |
| 41 |
of that group. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A local attacker could possibly run commands as an arbitrary system |
| 47 |
user (including root). |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All sudo users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.0" |
| 61 |
|
