Description |
39 |
=========== |
40 |
|
41 |
It has been identified that Mozilla Thunderbird improperly handles |
42 |
Script objects while they are being executed, allowing them to be |
43 |
modified during execution. JavaScript is disabled in Mozilla |
44 |
Thunderbird by default. Mozilla Thunderbird has also been found to be |
45 |
vulnerable to various potential buffer overflows. Lastly, the binary |
46 |
release of Mozilla Thunderbird is vulnerable to a low exponent RSA |
47 |
signature forgery issue because it is bundled with a vulnerable version |
48 |
of NSS. |
49 |
|
50 |
Impact |
51 |
====== |
52 |
|
53 |
An attacker could entice a user to view a specially crafted email that |
54 |
causes a buffer overflow and again executes arbitrary code or causes a |
55 |
Denial of Service. An attacker could also entice a user to view an |
56 |
email containing specially crafted JavaScript and execute arbitrary |
57 |
code with the rights of the user running Mozilla Thunderbird. It is |
58 |
important to note that JavaScript is off by default in Mozilla |
59 |
Thunderbird, and enabling it is strongly discouraged. It is also |
60 |
possible for an attacker to create SSL/TLS or email certificates that |
61 |
would not be detected as invalid by the binary release of Mozilla |
62 |
Thunderbird, raising the possibility for Man-in-the-Middle attacks. |
63 |
|
64 |
Workaround |
65 |
========== |
66 |
|
67 |
There is no known workaround at this time. |
68 |
|
69 |
Resolution |
70 |
========== |
71 |
|
72 |
Users upgrading to the following releases of Mozilla Thunderbird should |
73 |
note that this version of Mozilla Thunderbird has been found to not |
74 |
display certain messages in some cases. |
75 |
|
76 |
</br> |
77 |
|
78 |
</br> All Mozilla Thunderbird users should upgrade to the latest |
79 |
version: |
80 |
|
81 |
# emerge --sync |
82 |
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.5.0.8" |
83 |
|
84 |
All Mozilla Thunderbird binary release users should upgrade to the |
85 |
latest version: |
86 |
|
87 |
# emerge --sync |
88 |
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.5.0.8" |
