Versions of Mozilla Thunderbird prior to 2.0.0.19 are affected by the following vulnerabilities :

 - There are several stability bugs in the browser engine that may lead to crashes with evidence of memory corruption. (MFSA 2008-60)
 - XBL bindings can be used to read data from other domains. (MFSA 2008-61)
 - Sensitive data may be disclosed in an XHR response when an XMLHttpRequest is made to a same-origin resource, which 302 redirects to a resource in a different domain. (MFSA 2008-64)
 - A website may be able to access a limited amount of data from a different domain by loading a same-domain JavaScript URL that redirects to an off-domain target resource containing data that is not parsable as JavaScript. (MFSA 2008-65)
 - Errors arise when parsing URLs with leading whitespace and control characters. (MFSA 2008-66)
 - An escaped null byte is ignored by the CSS parser and treated as if it was not present in the CSS input string. (MFSA 2008-67)
 - XSS and JavaScript privilege escalation are possible. (MFSA 2008-68)
