Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Kurt Fitzner discovered that the NBD server allocates a request buffer |

Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could send a malicious request that can result in the |
| 46 |
execution of arbitrary code with the rights of the NBD server. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All NBD Tools users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=sys-block/nbd-2.8.2-r1" |
