Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The secure path feature and group handling in sudo allow local |
| 19 |
attackers to escalate privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
sudo allows a system administrator to give users the ability to run |
| 25 |
commands as other users. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been reported in sudo: |
| 39 |
|
| 40 |
* Evan Broder and Anders Kaseorg of Ksplice, Inc. reported that the |
| 41 |
sudo 'secure path' feature does not properly handle multiple PATH |
| 42 |
variables (CVE-2010-1646). |
| 43 |
|
| 44 |
* Markus Wuethrich of Swiss Post reported that sudo fails to restrict |
| 45 |
access when using Runas groups and the group (-g) command line option |
| 46 |
(CVE-2010-2956). |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A local attacker could exploit these vulnerabilities to gain the |
| 52 |
ability to run certain commands with the privileges of other users, |
| 53 |
including root, depending on the configuration. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All sudo users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.4_p3-r1" |
| 67 |
|
