Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 3.6.24 Thunderbird versions prior to 3.1.6

Description The issue arises from the JSSubScriptLoader in Mozilla Firefox and Thunderbird, which does not properly handle XPCNativeWrappers during calls to the loadSubScript method in an add-on. This makes it easier for remote attackers to gain privileges via a crafted web site that leverages certain unwrapping behavior.

Recommendations For Mozilla Firefox versions prior to 3.6.24, update to version 3.6.24 or later. For Thunderbird versions prior to 3.1.6, update to version 3.1.6 or later.
