Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 61.0.3163.79 for Mac, Windows, and Linux Google Chrome version prior to 61.0.3163.81 for Android

Description The issue allows a remote attacker to potentially downgrade HTTPS requests to HTTP via a crafted HTML page, causing the browser to transmit cleartext even when the user enters an https URL. This is due to a misdesigned workaround for cases where the domain name in a URL almost matches the domain name in an X.509 server certificate, differing only in the initial "www." substring.

Recommendations For Google Chrome versions prior to 61.0.3163.79 on Mac, Windows, and Linux, update to version 61.0.3163.79 or later. For Google Chrome version prior to 61.0.3163.81 on Android, update to version 61.0.3163.81 or later.
