Synopsis

A web browser installed on the remote macOS host is affected by multiple vulnerabilities.

Description

The version of Google Chrome installed on the remote macOS host is prior to 85.0.4183.121. It is, therefore, affected by multiple vulnerabilities as referenced in the 2020_09_stable-channel-update-for-desktop_21 advisory.

 - Type confusion in V8 in Google Chrome prior to 85.0.4183.121 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (CVE-2020-15965)

 - Insufficient policy enforcement in extensions in Google Chrome prior to 85.0.4183.121 allowed an attacker who convinced a user to install a malicious extension to potentially perform a sandbox escape via a crafted Chrome Extension. (CVE-2020-15963)
