Description |
| 43 |
=========== |
| 44 |
|
| 45 |
Martijn Wargers and Nick Mott discovered a vulnerability when rendering |
| 46 |
malformed JavaScript content. The Mozilla Firefox 1.0 line is not |
| 47 |
affected. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
If JavaScript is enabled, by tricking a user into visiting a malicious |
| 53 |
web page which would send a specially crafted HTML script that contains |
| 54 |
references to deleted objects with the "designMode" property enabled, |
| 55 |
an attacker can crash the web browser and in theory manage to execute |
| 56 |
arbitrary code with the rights of the user running the browser. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
