Doc Text:
A flaw was found in the chromium-browser ServiceWorker component. A remote attacker could exploit this flaw to execute arbitrary code within the browser sandbox by enticing a user to visit a specially crafted HTML page. This issue stems from a use-after-free memory corruption condition, which occurs when the application attempts to reference memory that has already been deallocated.
