Description |
| 40 |
=========== |
| 41 |
|
| 42 |
The following vulnerabilities were found and fixed in Mozilla Firefox: |
| 43 |
|
| 44 |
* "moz_bug_r_a4" and "shutdown" discovered that Firefox was |
| 45 |
improperly cloning base objects (MFSA 2005-56). |
| 46 |
|
| 47 |
* Michael Krax reported that Firefox was not correctly handling |
| 48 |
JavaScript URLs from external applications (MFSA 2005-53), and that |
| 49 |
the "Set as wallpaper" function in versions 1.0.3 and 1.0.4 could be |
| 50 |
abused to load JavaScript (MFSA 2005-47). |
| 51 |
|
| 52 |
* Several researchers reported ways to trick Firefox into accepting |
| 53 |
events generated by web content (MFSA 2005-45). |
| 54 |
|
| 55 |
* Kohei Yoshino discovered a new way to inject script from the |
| 56 |
sidebar panel using data: (MFSA 2005-49). |
| 57 |
|
| 58 |
* "moz_bug_r_a4" reported that Firefox failed to validate XHTML DOM |
| 59 |
nodes properly (MFSA 2005-55), and that XBL scripts ran even when |
| 60 |
Javascript is disabled (MFSA 2005-46). |
| 61 |
|
| 62 |
* "shutdown" discovered a possibly exploitable crash in |
| 63 |
InstallVersion.compareTo (MFSA 2005-50). |
| 64 |
|
| 65 |
* Finally, Secunia discovered that a child frame can call top.focus() |
| 66 |
even if the framing page comes from a different origin and has |
| 67 |
overridden the focus() routine (MFSA 2005-52), and that the frame |
| 68 |
injection spoofing bug fixed in 1.0.2 was mistakenly reintroduced in |
| 69 |
1.0.3 and 1.0.4 (MFSA 2005-51). |
| 70 |
|
| 71 |
Impact |
| 72 |
====== |
| 73 |
|
| 74 |
A remote attacker could craft malicious web pages that would leverage |
| 75 |
these issues to inject and execute arbitrary script code with elevated |
| 76 |
privileges, steal cookies or other information from web pages, or spoof |
| 77 |
content. |
| 78 |
|
| 79 |
Workaround |
| 80 |
========== |
| 81 |
|
| 82 |
There are no known workarounds for all the issues at this time. |
| 83 |
|
| 84 |
