Mozilla released a new version of Mozilla Firefox. The latest version offers protection against a vulnerability found by security researcher Samuel Groß (CVE-2019-11707).
The vulnerability in Firefox made it possible for an attacker to gain control over the device by viewing an infected advertisement.
Mozilla does not provide any further information about the vulnerability but Mozilla is aware of targeted attacks on users who are using an older version of Firefox.
It is important to update Firefox to Firefox 67.0.3 and Firefox ESR 60.7.1 as soon as possible.
In both versions, the Firefox security leak was fixed and users are no longer susceptible to this vulnerability in Firefox.
