Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities may allow the execution of arbitrary code. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
Opera is a multi-platform web browser. |
| 24 |
|
| 25 |
Affected packages |
| 26 |
================= |
| 27 |
|

| 29 |
Package / Vulnerable / Unaffected |

|
| 33 |
Description |
| 34 |
=========== |
| 35 |
|
| 36 |
Christoph Deal discovered that JPEG files with a specially crafted DHT |
| 37 |
marker can be exploited to cause a heap overflow. Furthermore, an |
| 38 |
anonymous person discovered that Opera does not correctly handle |
| 39 |
objects passed to the "createSVGTransformFromMatrix()" function. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could potentially exploit the vulnerabilities to execute |
| 45 |
arbitrary code with the privileges of the user running Opera by |
| 46 |
enticing a victim to open a specially crafted JPEG file or a website |
| 47 |
containing malicious JavaScript code. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
The vendor recommends disabling JavaScript to avoid the |
| 53 |
"createSVGTransformFromMatrix" vulnerability. There is no known |
| 54 |
workaround for the other vulnerability. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All Opera users should update to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=www-client/opera-9.10" |
| 63 |
