  - A memory corruption vulnerability exists. The

    framesets when unloading a page. An attacker could 
    craft a web page that will trigger the vulnerability 
    which may allow arbitrary code execution.

    crashes. Affected items or functionality include 
    unspecified web content, reloading pages after opening
    a pop-up from the Easy Sticky Note extension, handling
    of the column-count CSS property, destruction of a
    Silverlight instance, the handling of Certificate
