Chromium

Chromium is an open-source software project from Google that forms the foundation for several web browsers, including Google Chrome and Microsoft Edge. This software provides the essential framework upon which these browsers are built, offering features such as rendering and JavaScript processing via its V8 engine. However, Chromium has faced security vulnerabilities over time. For instance, CVE-2023-2033 and CVE-2023-3079 were type confusion vulnerabilities in the Google Chromium V8 engine that could potentially allow a remote attacker to exploit heap corruption via a crafted HTML page. Similarly, CVE-2024-7971 was another type confusion issue in the V8 engine, impacting JavaScript execution in Chrome and other Chromium-based browsers. On June 16, 2020, Windows 10 Insider Preview Build 19042.330 for 20H2 was released, marking the first Windows Insider Preview build for the next Windows 10 upgrade, code-named 20H2. This update included fixes from the KB4557957 (OS Build 19041.329) build for the Windows 10 May 2020 Update, as well as the new Microsoft Edge based on Chromium. However, this integration wasn't without its challenges. A high-severity bug, CVE-2024-38106, was exploited by Citrine Sleet in Chromium, leading to a chain of exploits. Moreover, users who connected to a certain domain automatically triggered a zero-day memory corruption exploit in Chromium. Despite these vulnerabilities, Chromium remains a fundamental part of many modern web browsers. It's important to note that not all browsers use the Chromium engine; Firefox, for example, uses a different browser engine. The growing dependence on Chromium has led to efforts to enhance its security. One such effort was Google's release of an update to Chrome on August 21, which included 38 security fixes. Many companies have also realized the potential of Chromium, using it as a base to build their own browsers with additional features such as URL filtering, malware analysis, and data loss prevention.
