Impact |
| 42 |
====== |
| 43 |
|
| 44 |
Successful exploitation of this vulnerability may allow an |
| 45 |
unauthenticated remote attacker to execute arbitrary code with the |
| 46 |
permissions of the Tor user, or to cause a Denial of Service. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |

Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Tor users should upgrade to the latest stable version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.2.1.28" |
