Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
The NVIDIA binary graphics driver is vulnerable to a local privilege |
| 20 |
escalation through an X session. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
The NVIDIA binary graphics driver from NVIDIA Corporation provides the |
| 26 |
kernel module and the GL modules for graphic acceleration on the NVIDIA |
| 27 |
based graphic cards. |
| 28 |
|
| 29 |
Affected packages |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
Rapid7 reported a boundary error in the NVIDIA binary graphics driver |
| 42 |
that leads to a buffer overflow in the accelerated rendering |
| 43 |
functionality. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
An X client could trigger the buffer overflow with a maliciously |
| 49 |
crafted series of glyphs. A remote attacker could also entice a user to |
| 50 |
open a specially crafted web page, document or X client that will |
| 51 |
trigger the buffer overflow. This could result in the execution of |
| 52 |
arbitrary code with root privileges or at least in the crash of the X |
| 53 |
server. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
Disable the accelerated rendering functionality in the Device section |
| 59 |
of xorg.conf : |
| 60 |
Option "RenderAccel" "false" |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
NVIDIA binary graphics driver users should upgrade to the latest |
| 66 |
version: |
| 67 |
|
| 68 |
# emerge --sync |
| 69 |
# emerge --ask --oneshot --verbose ">=x11-drivers/nvidia-drivers-1.0.8776" |
| 70 |
