  - The 'tdc.ocx' ActiveX control being built with vulnerable Active Template
    Library (ATL) headers, which could allow the instantiation of arbitrary objects

  - Memory corruption error occurs when the browser attempts to access an object
    that has not been initialized or has been deleted, which could be exploited
    to execute arbitrary code via a specially crafted web page.

  - Memory corruption occurs when processing 'CSS' objects.

  - Race condition occurs while repetitively clicking between two elements at
    a fast rate, which could be exploited to execute arbitrary code via a
    specially crafted web page.

  - A dangling pointer during deallocation of a circular dereference for a
    CAttrArray object, which could be exploited to execute arbitrary code via
    a specially crafted web page.");
