Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The GnomeVFS and libcdaudio libraries contain a buffer overflow that |
| 19 |
can be triggered by a large CDDB response, potentially allowing the |
| 20 |
execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
GnomeVFS is a filesystem abstraction library for the GNOME desktop |
| 26 |
environment. libcdaudio is a multi-platform CD player development |
| 27 |
library. They both include code to query CDDB servers to get Audio CD |
| 28 |
track titles. |

Description |
| 43 |
=========== |
| 44 |
|
| 45 |
Joseph VanAndel has discovered a buffer overflow in Grip when |
| 46 |
processing large CDDB results (see GLSA 200503-21). The same overflow |
| 47 |
is present in GnomeVFS and libcdaudio code. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
A malicious CDDB server could cause applications making use of GnomeVFS |
| 53 |
or libcdaudio libraries to crash, potentially allowing the execution of |
| 54 |
arbitrary code with the privileges of the user running the application. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All GnomeVFS users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=gnome-base/gnome-vfs-2.8.4-r1" |
| 68 |
|
| 69 |
All libcdaudio users should upgrade to the latest version: |
| 70 |
|
| 71 |
# emerge --sync |
| 72 |
# emerge --ask --oneshot --verbose ">=media-libs/libcdaudio-0.99.10-r1" |
| 73 |
