Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Kaffeine and gxine both contain a buffer overflow that can be exploited |
| 19 |
when accessing content from a malicious HTTP server with specially |
| 20 |
crafted headers. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Kaffeine and gxine are graphical front-ends for xine-lib multimedia |
| 26 |
library. |
| 27 |
|
| 28 |
Affected packages |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
KF of Secure Network Operations has discovered an overflow that occurs |
| 45 |
during the Content-Type header processing of Kaffeine. The vulnerable |
| 46 |
code in Kaffeine is reused from gxine, making gxine vulnerable as well. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
An attacker could create a specially-crafted Content-type header from a |
| 52 |
malicious HTTP server, and crash a user's instance of Kaffeine or |
| 53 |
gxine, potentially allowing the execution of arbitrary code. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All Kaffeine users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=media-video/kaffeine-0.4.3b-r1" |
| 67 |
|
| 68 |
All gxine users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=media-video/gxine-0.3.3-r1" |
| 72 |
