Technical details

An address spoofing vulnerability exists in the Google Chrome Omnibox component due to improper input validation of invalid URLs. By enticing a user to visit a specially crafted HTML page, a remote attacker can manipulate the displayed URL in the address bar without navigating to that actual location. This flaw stems from incorrect handling of malformed URL strings, which fails to trigger appropriate security UI indicators or reverts to an incorrect state. The vulnerability was patched in Chrome version 55.0.2883.75 for desktop platforms and 55.0.2883.84 for Android.
