Synopsis |
16 |
======== |
17 |
|
18 |
Several vulnerabilities in the Mozilla Suite and Firefox allow an |
19 |
attacker to conduct cross-site scripting attacks or to execute |
20 |
arbitrary code. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
The Mozilla Suite is a popular all-in-one web browser that includes a |
26 |
mail and news reader. Mozilla Firefox is the next-generation browser |
27 |
from the Mozilla project. |

Description |
44 |
=========== |
45 |
|
46 |
The Mozilla Suite and Firefox do not properly protect "IFRAME" |
47 |
JavaScript URLs from being executed in context of another URL in the |
48 |
history list (CAN-2005-1476). The Mozilla Suite and Firefox also fail |
49 |
to verify the "IconURL" parameter of the "InstallTrigger.install()" |
50 |
function (CAN-2005-1477). Michael Krax and Georgi Guninski discovered |
51 |
that it is possible to bypass JavaScript-injection security checks by |
52 |
wrapping the javascript: URL within the view-source: or jar: |
53 |
pseudo-protocols (MFSA2005-43). |
54 |
|
55 |
Impact |
56 |
====== |
57 |
|
58 |
A malicious remote attacker could use the "IFRAME" issue to execute |
59 |
arbitrary JavaScript code within the context of another website, |
60 |
allowing to steal cookies or other sensitive data. By supplying a |
61 |
javascript: URL as the "IconURL" parameter of the |
62 |
"InstallTrigger.Install()" function, a remote attacker could also |
63 |
execute arbitrary JavaScript code. Combining both vulnerabilities with |
64 |
a website which is allowed to install software or wrapping javascript: |
65 |
URLs within the view-source: or jar: pseudo-protocols could possibly |
66 |
lead to the execution of arbitrary code with user privileges. |
67 |
|
68 |
Workaround |
69 |
========== |
70 |
|
71 |
Affected systems can be protected by disabling JavaScript. However, we |
72 |
encourage Mozilla Suite or Mozilla Firefox users to upgrade to the |
73 |
latest available version. |
74 |
|
75 |
Resolution |
76 |
========== |
77 |
|
78 |
All Mozilla Firefox users should upgrade to the latest version: |
79 |
|
80 |
# emerge --sync |
81 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.4" |
82 |
|
83 |
All Mozilla Firefox binary users should upgrade to the latest version: |
84 |
|
85 |
# emerge --sync |
86 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.0.4" |
87 |
|
88 |
All Mozilla Suite users should upgrade to the latest version: |
89 |
|
90 |
# emerge --sync |
91 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.8" |
92 |
|
93 |
All Mozilla Suite binary users should upgrade to the latest version: |
94 |
|
95 |
# emerge --sync |
96 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-bin-1.7.8" |
