Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities in NVIDIA drivers may allow a local attacker to |
| 19 |
gain escalated privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic |
| 25 |
boards. |
| 26 |
|
| 27 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Two vulnerabilities have been discovered in NVIDIA drivers: |
| 40 |
|
| 41 |
* A vulnerability has been found in the way NVIDIA drivers handle |
| 42 |
read/write access to GPU device nodes, allowing access to arbitrary |
| 43 |
system memory locations (CVE-2012-4225). |
| 44 |
* A buffer overflow error has been discovered in NVIDIA drivers |
| 45 |
(CVE-2013-0131). |
| 46 |
|
| 47 |
NOTE: Exposure to CVE-2012-4225 is reduced in Gentoo due to 660 |
| 48 |
permissions being used on the GPU device nodes by default. |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A local attacker could gain escalated privileges. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All NVIDIA driver users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot -v ">=x11-drivers/nvidia-drivers-304.88" |
| 67 |
