Mozilla Thunderbird Multiple Vulnerabilities Mar-09 (Windows)

The host is installed with Mozilla Thunderbird and is prone to multiple vulnerabilities.

Multiple flaws due to, - Layout engine error which causes memory corruption and assertion failures. - Layout engine error related to 'nsCSSStyleSheet::GetOwnerNode', events and garage collection which triggers memory corruption. - Layout engine error through a splice of an array that contains 'non-set' elements which causes 'jsarray.cpp' to pass an incorrect argument to the 'ResizeSlots' function which causes application crash. - Vectors related to js_DecompileValueGenerator, jsopcode.cpp, __defineSetter__ and watch which causes a segmentation fault. - Layout engine error in the vector related to 'gczeal'. - Double free vulnerability in Thunderbird via 'cloned XUL DOM elements' which were linked as a parent and child are not properly handled during garbage collection which causes arbitrary code execution. - 'nsIRDFService' in Thunderbird allows to bypass the same origin policy and read XML data through another domain by cross-domain redirect. - Error while decoding invisible characters when they are displayed in the location bar which causes incorrect address to be displayed in the URL bar and causes spoofing attacks.
