Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
A race condition in polkit could allow a local attacker to gain |
| 20 |
escalated privileges. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
polkit is a toolkit for managing policies relating to unprivileged |
| 26 |
processes communicating with privileged processes. |
| 27 |

Description |
| 43 |
=========== |
| 44 |
|
| 45 |
polkit has a race condition which potentially allows a process to |
| 46 |
change its UID/EUID via suid or pkexec before authentication is |
| 47 |
completed. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
A local attacker could start a suid or pkexec process through a |
| 53 |
polkit-enabled application, which could result in privilege escalation |
| 54 |
or bypass of polkit restrictions. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
