Google has released updates for Chrome and Chrome OS. These updates fix several vulnerabilities present in versions earlier than 46.0.2490.86 for Windows, Mac and Linux, and 46.0.2490.82 for all OS devices.
One of the vulnerabilities addressed is an information leakage bug in Chrome’s built-in PDF reader. An attacker could exploit this flaw to bypass protection mechanisms and launch code on the victim’s computer.
Full details of the vulnerabilities are not yet available as Google withholds this information until most Chrome users have updated their systems. This process makes it harder for attackers to exploit vulnerabilities before users have installed the updates.
Users of Chrome and Chrome OS are advised to update their systems as soon as possible, and to ensure that updates are set to automatically apply when available.
