Synopsis |

|
| 18 |
The Mozilla Foundation has reported numerous security vulnerabilities |
| 19 |
related to Mozilla Firefox. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Mozilla Firefox is a redesign of the Mozilla Navigator component. The |

Description |
| 40 |
=========== |
| 41 |
|
| 42 |
The following vulnerabilities have been reported: |
| 43 |
|
| 44 |
* Benjamin Smedberg discovered that chrome URL's could be made to |
| 45 |
reference remote files. |
| 46 |
|
| 47 |
* Developers in the Mozilla community looked for and fixed several |
| 48 |
crash bugs to improve the stability of Mozilla clients. |
| 49 |
|
| 50 |
* "shutdown" reports that cross-site scripting (XSS) attacks could be |
| 51 |
performed using the construct XPCNativeWrapper(window).Function(...), |
| 52 |
which created a function that appeared to belong to the window in |
| 53 |
question even after it had been navigated to the target site. |
| 54 |
|
| 55 |
* "shutdown" reports that scripts granting the UniversalBrowserRead |
| 56 |
privilege can leverage that into the equivalent of the far more |
| 57 |
powerful UniversalXPConnect since they are allowed to "read" into a |
| 58 |
privileged context. |
| 59 |
|
| 60 |
* "moz_bug_r_a4" reports that A malicious Proxy AutoConfig (PAC) |
| 61 |
server could serve a PAC script that can execute code with elevated |
| 62 |
privileges by setting the required FindProxyForURL function to the |
| 63 |
eval method on a privileged object that leaked into the PAC sandbox. |
| 64 |
|
| 65 |
* "moz_bug_r_a4" discovered that Named JavaScript functions have a |
| 66 |
parent object created using the standard Object() constructor |
| 67 |
(ECMA-specified behavior) and that this constructor can be redefined |
| 68 |
by script (also ECMA-specified behavior). |
| 69 |
|
| 70 |
* Igor Bukanov and shutdown found additional places where an untimely |
| 71 |
garbage collection could delete a temporary object that was in active |
| 72 |
use. |
| 73 |
|
| 74 |
* Georgi Guninski found potential integer overflow issues with long |
| 75 |
strings in the toSource() methods of the Object, Array and String |
| 76 |
objects as well as string function arguments. |
| 77 |
|
| 78 |
* H. D. Moore reported a testcase that was able to trigger a race |
| 79 |
condition where JavaScript garbage collection deleted a temporary |
| 80 |
variable still being used in the creation of a new Function object. |
| 81 |
|
| 82 |
* A malicious page can hijack native DOM methods on a document object |
| 83 |
in another domain, which will run the attacker's script when called |
| 84 |
by the victim page. |
| 85 |
|
| 86 |
* Secunia Research has discovered a vulnerability which is caused due |
| 87 |
to an memory corruption error within the handling of simultaneously |
| 88 |
happening XPCOM events. This leads to use of a deleted timer object. |
| 89 |
|
| 90 |
* An anonymous researcher for TippingPoint and the Zero Day |
| 91 |
Initiative showed that when used in a web page Java would reference |
| 92 |
properties of the window.navigator object as it started up. |
| 93 |
|
| 94 |
* Thilo Girmann discovered that in certain circumstances a JavaScript |
| 95 |
reference to a frame or window was not properly cleared when the |
| 96 |
referenced content went away. |
| 97 |
|
| 98 |
Impact |
| 99 |
====== |
| 100 |
|
| 101 |
A user can be enticed to open specially crafted URLs, visit webpages |
| 102 |
containing malicious JavaScript or execute a specially crafted script. |
| 103 |
These events could lead to the execution of arbitrary code, or the |
| 104 |
installation of malware on the user's computer. |
| 105 |
|
| 106 |
Workaround |
| 107 |
========== |
| 108 |
|
| 109 |
There is no known workaround at this time. |
| 110 |
|
| 111 |
Resolution |
| 112 |
========== |
| 113 |
|
| 114 |
All Mozilla Firefox users should upgrade to the latest version: |
| 115 |
|
| 116 |
# emerge --sync |
| 117 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.5.0.5" |
| 118 |
|
| 119 |
Users of the binary package should upgrade as well: |
| 120 |
|
| 121 |
# emerge --sync |
| 122 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.5" |
| 123 |
