Description

Google Chrome contains a use-after-free error in the Safe Browsing feature as the current NavigationEntry is deleted when leaving an interstitial page. The issue is triggered when e.g. reloading a web page that displays the malware blocking page. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
