Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Konstantine Shirow reported a vulnerability in default Gentoo |
| 38 |
configurations of Festival. The daemon is configured to run with root |
| 39 |
privileges and to listen on localhost, without requiring a password. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A local attacker could gain root privileges by connecting to the daemon |
| 45 |
and execute arbitrary commands. |
| 46 |
|
| 47 |
Workaround |
| 48 |
========== |
| 49 |
|
| 50 |
Set a password in the configuration file /etc/festival/server.scm by |
| 51 |
adding the line: (set! server_passwd password) |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Festival users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=app-accessibility/festival-1.95_beta-r4" |
