Description |
| 41 |
=========== |
| 42 |
|
| 43 |
The following vulnerabilities were found and fixed in Mozilla |
| 44 |
Thunderbird: |
| 45 |
|
| 46 |
* "moz_bug_r_a4" and "shutdown" discovered that Thunderbird was |
| 47 |
improperly cloning base objects (MFSA 2005-56). |
| 48 |
|
| 49 |
* "moz_bug_r_a4" also reported that Thunderbird was overly trusting |
| 50 |
contents, allowing privilege escalation via property overrides (MFSA |
| 51 |
2005-41, 2005-44), that it failed to validate XHTML DOM nodes |
| 52 |
properly (MFSA 2005-55), and that XBL scripts ran even when |
| 53 |
Javascript is disabled (MFSA 2005-46). |
| 54 |
|
| 55 |
* "shutdown" discovered a possibly exploitable crash in |
| 56 |
InstallVersion.compareTo (MFSA 2005-50). |
| 57 |
|
| 58 |
* Andreas Sandblad from Secunia reported that a child frame can call |
| 59 |
top.focus() even if the framing page comes from a different origin |
| 60 |
and has overridden the focus() routine (MFSA 2005-52). |
| 61 |
|
| 62 |
* Georgi Guninski reported missing Install object instance checks in |
| 63 |
the native implementations of XPInstall-related JavaScript objects |
| 64 |
(MFSA 2005-40). |
| 65 |
|
| 66 |
* Finally, Vladimir V. Perepelitsa discovered a memory disclosure bug |
| 67 |
in JavaScript's regular expression string replacement when using an |
| 68 |
anonymous function as the replacement argument (CAN-2005-0989 and |
| 69 |
MFSA 2005-33). |

|
| 71 |
Impact |
| 72 |
====== |
| 73 |
|
| 74 |
A remote attacker could craft malicious email messages that would |
| 75 |
leverage these issues to inject and execute arbitrary script code with |
| 76 |
elevated privileges or help in stealing information. |
| 77 |
|
| 78 |
Workaround |
| 79 |
========== |
| 80 |
|
| 81 |
There are no known workarounds for all the issues at this time. |
| 82 |
|
| 83 |

| 91 |
|
| 92 |
