Firefox web browsers had very critical vulnerabilities that have been already exploited by the attackers. However, the company has just pushed an update to fix this which users are advised to install immediately.
The company pushed Firefox 74.0.1 update to fix this vulnerability. This new Firefox version includes fixes for CVE-2020-6819 and CVE-2020-6820, two bugs that reside in the way Firefox manages its memory space.
According to Mozilla, these two vulnerabilities are of the ‘use-after-free’ type and can be in use to execute an attacker’s code in the browser on the user’s system. These bugs can be exploited to run code on victim’s devices, although there is no information on how it reaches and impact the victim’s system.
Mozilla credited security firm JMP Security and security researcher Francisco Alonso with discovering the two zero-days. In a tweet today, Alonso suggested that the bugs discovered today might also impact other browsers, however, there is no information whether other browsers have got some impact by this vulnerability or not.
This is the second immediate patch for Mozilla’s browser for this year. Earlier in January, the company had patched a critical bug with the immediate release of Firefox v72.0.1.
