Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two errors in udev allow for a local root compromise and a Denial of |
| 19 |
Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
udev is the device manager used in the Linux 2.6 kernel series. |
| 25 |
|
| 26 |
Affected packages |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Sebastian Krahmer of SUSE discovered the following two vulnerabilities: |
| 38 |
|
| 39 |
* udev does not verify the origin of NETLINK messages properly |
| 40 |
(CVE-2009-1185). |
| 41 |
|
| 42 |
* A buffer overflow exists in the util_path_encode() function in |
| 43 |
lib/libudev-util.c (CVE-2009-1186). |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A local attacker could gain root privileges by sending specially |
| 49 |
crafted NETLINK messages to udev or cause 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 udev users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=sys-fs/udev-124-r2" |
| 63 |
