Synopsis :

The remote Windows host contains a mail client that is affected by
multiple vulnerabilities.

Description :

The installed version of Thunderbird is affected by various security
issues :

- Using a specially crafted UTF-8 URL in a hyperlink, an
attacker might be able to exploit a stack buffer
overflow in the Mozilla URL parsing routes to execute
arbitrary code (MFSA 2008-37).

- It is possible to bypass the same-origin check in
'nsXMLDocument::OnChannelRedirect()' (MFSA 2008-38).

- Privilege escalation is possible via 'XPCnativeWrapper'
pollution (MFSA 2008-41).

- There are several stability bugs in the browser engine
that coould lead to crashes with evidence of memory
corruption (MFSA 2008-42).

- Certain BOM characters and low surrogate characters,
if HTML-escaped, are stripped from JavaScript code
before it is executed, which could allow for cross-
site scripting attacks (MFSA 2008-43).

- The 'resource:' protocol allows directory traversal
on Linux when using URL-encoded slashes, and it can
be used to bypass restrictions on local HTML files
(MFSA 2008-44).

- There is a heap buffer overflow that can be triggered
when canceling a newsgroup message (MFSA 2008-46).
