Details

Several flaws were discovered in the browser engine. If a user had Javascript
enabled, these problems could allow an attacker to crash Thunderbird and
possibly execute arbitrary code with user privileges. (CVE-2008-5500)

Boris Zbarsky discovered that the same-origin check in Thunderbird could be
bypassed by utilizing XBL-bindings. If a user had Javascript enabled, an
attacker could exploit this to read data from other domains. (CVE-2008-5503)

Marius Schilder discovered that Thunderbird did not properly handle redirects
to an outside domain when an XMLHttpRequest was made to a same-origin resource.
When Javascript is enabled, it’s possible that sensitive information could be
revealed in the XMLHttpRequest response. (CVE-2008-5506)

Chris Evans discovered that Thunderbird did not properly protect a user’s data
when accessing a same-domain Javascript URL that is redirected to an unparsable
Javascript off-site resource. If a user were tricked into opening a malicious
website and had Javascript enabled, an attacker may be able to steal a limited
amount of private data. (CVE-2008-5507)

Chip Salzenberg, Justin Schuh, Tom Cross, and Peter William discovered
Thunderbird did not properly parse URLs when processing certain control
characters. (CVE-2008-5508)

Kojima Hajime discovered that Thunderbird did not properly handle an escaped
null character. An attacker may be able to exploit this flaw to bypass script
sanitization. (CVE-2008-5510)

Several flaws were discovered in the Javascript engine. If a user were tricked
into opening a malicious website and had Javascript enabled, an attacker could
exploit this to execute arbitrary Javascript code within the context of another
website or with chrome privileges. (CVE-2008-5511, CVE-2008-5512)
