Google Chrome Zero-Day Vulnerability

Google has released Chrome 86.0.4240.111 today to patch high-severity issues, including a zero-day vulnerability that has been exploited in the wild. This is currently impacting Windows, Linux and Mac OS.

The vulnerability (CVE-2020-15999) is a memory-corruption flaw called heap buffer overflow in Freetype, an open-source software development library for rendering fonts included with Chrome.

According to researchers, the vulnerability is in the FreeType’s function “Load_SBit_Png,” which processes PNG images embedded into fonts. It can be exploited by attackers to execute arbitrary code through specific fonts with embedded PNG images.

Patching the Chrome Vulnerabilities

Google released Chrome 86.0.4240.111 as Chrome’s “stable” version, which is available to all users. The company stated that “an exploit for CVE-2020-15999 exists in the wild,” but did not reveal the latest attack details.

Besides the FreeType zero-day vulnerability, Google also patched four other severe flaws in the latest Chrome update.

The following issues have been resolved:

  • CVE-2020-16000: Inappropriate implementation in Blink
  • CVE-2020-16001: Use after free in media
  • CVE-2020-15999: Heap buffer overflow in Freetype
  • CVE-2020-16003: Use after free in printing

Google Releases Chrome 86 with Critical Fixes

Google has leased its Stable channel version of Google Chrome 86. Contained within this release includes a massive amount of updates and bug fixes for security, features and API. This version is supported on both Windows, Android, Mac and Linux.

However, a critical flaw (CVE-2020-15967) in Chrome’s payments component has a CVSS score of 9.8, making this a Zero Day vulnerability. This severity rating means Google is recommending you deploy this version as soon as possible.

The flaw is a use-after-free bug. Use after free is a memory-corruption flaw where an attempt is made to access memory after it has been freed. This can cause malicious impacts, from making a program to crash to potentially leading to arbitrary code execution.

Use-after-free bugs have been a frequent threat to the browser. Seven high-severity vulnerabilities fixed in Chrome 86 were use-after-free flaws, from ones affecting Chrome’s printing (CVE-2020-15971), audio (CVE-2020-15972), password manager (CVE-2020-15991) and WebRTC (CVE-2020-15969) components.

Customers of Syxsense Manage and Syxsense Secure can find these updates within the console.
