Attention readers, if you are using Google Chrome browser on your Windows, Mac, or Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today.

Google released Chrome version 86.0.4240.111 today to patch several security high-severity issues, including a zero-day vulnerability that has been exploited in the wild by attackers to hijack targeted computers.

Tracked as CVE-2020-15999, the actively exploited vulnerability is a type of memory-corruption flaw called heap buffer overflow in Freetype, a popular open source software development library for rendering fonts that comes packaged with Chrome.

The vulnerability was discovered and reported by security researcher Sergei Glazunov of Google Project Zero on October 19 and is subject to a seven-day public disclosure deadline due to the flaw being under active exploitation.

Glazunov also immediately reported the zero-day vulnerability to FreeType developers, who then developed an emergency patch to address the issue on October 20 with the release of FreeType 2.10.4.

Without revealing technical details of the vulnerability, the technical lead for Google’s Project Zero Ben Hawkes warned on Twitter that while the team has only spotted an exploit targeting Chrome users, it’s possible that other projects that use FreeType might also be vulnerable and are advised to deploy the fix included in FreeType version 2.10.4.
