Ravens PHP Scripts - Mozilla Thunderbird Multiple Vulnerabilities

SECUNIA ADVISORY ID: SA22770

VERIFY ADVISORY: http://secunia.com/advisories/22770/

CRITICAL: Moderately critical

IMPACT: Security Bypass, Cross Site Scripting, DoS, System access

WHERE: >From remote

SOFTWARE: Mozilla Thunderbird 1.5.x - http://secunia.com/product/4652/

DESCRIPTION: Some vulnerabilities have been reported in Mozilla Thunderbird, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, and potentially compromise a vulnerable system.

1) The bundled Network Security Services (NSS) library contains an incomplete fix for the RSA signature verification vulnerability reported in MFSA 2006-60.

For more information: SA21903

2) An error exists within the handling of Script objects. This can be potentially be exploited to execute arbitrary JavaScript bytecode by modifying already running Script objects. Successful exploitation requires that JavaScript is enabled.

3) Some unspecified errors in the layout engine and memory corruption errors in the JavaScript engine can be exploited to crash the application and may allow the execution of arbitrary code. Successful exploitation of some of these vulnerabilities requires that JavaScript is enabled.

4) An unspecified error within XML.prototype.hasOwnProperty can potentially be exploited to execute arbitrary code.

SOLUTION: Update to Mozilla Thunderbird 1.5.0.8.
