Mozilla Firefox and SeaMonkey contain a flaw related to the js3250.dll library encountering an error when processing the 'JSON.stringify()' method. The issue is triggered when a context-dependent attacker uses an invalid pointer in a call to the 'js_HasOwnProperty()' function to dereference an invalid pointer. This may allow an attacker to execute arbitrary code.
