Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability has been discovered in BEAST allowing for a Denial of |
| 19 |
Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
BEdevilled Audio SysTem is an audio compositor, supporting a wide range |
| 25 |
of audio formats. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-sound/beast < 0.7.1 >= 0.7.1 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
BEAST, which is installed as setuid root, fails to properly check |
| 39 |
whether it can drop privileges accordingly if seteuid() fails due to a |
| 40 |
user exceeding assigned resource limits. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A local user could exceed his resource limit in order to prevent the |
| 46 |
seteuid() call from succeeding. This may lead BEAST to keep running |
| 47 |
with root privileges. Then, the local user could use the "save as" |
| 48 |
dialog box to overwrite any file on the vulnerable system, potentially |
| 49 |
leading to a Denial of Service. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All BEAST users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=media-sound/beast-0.7.1" |
| 63 |
|
