TITLE:
Mozilla Thunderbird XBL Controls Script Execution Vulnerability

SECUNIA ADVISORY ID:
SA16062

VERIFY ADVISORY:
http://secunia.com/advisories/16062/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Mozilla Thunderbird 0.x
http://secunia.com/product/2637/
Mozilla Thunderbird 1.x
http://secunia.com/product/4652/

DESCRIPTION:
moz_bug_r_a4 has reported a vulnerability in Thunderbird, which can
be exploited by malicious people to bypass certain security
restrictions.

The problem is that scripts in XBL controls in e-mails can be
executed even when JavaScript has been disabled (JavaScript is
disabled by default). This does not pose any direct security risks by
itself, but may enable exploitation of vulnerabilities requiring
JavaScript.

SOLUTION:
Do not open mails from untrusted sources.

The vulnerability has been fixed in the CVS repository and will be
included in the upcoming 1.0.5 release.
