The types include Use After Free and Heap-based Buffer Overflow. In the most severe case, an unauthenticated remote attacker may induce a user to open a specially crafted HTML page, and then execute arbitrary code within the browser sandbox environment. Please confirm and perform patching as soon as possible.
