| Descripción: | Summary:
Mozilla Thunderbird is prone to multiple vulnerabilities.
Vulnerability Insight:
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.

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.

location bar which causes incorrect address to be displayed in the URL bar
