![]() ![]() Here's a list of the Chrome desktop updates in the past six months of 2021. However, both Brave and Vivaldi have updated themselves to the current version of Chromium. 63, while Opera was even further back with Chromium. 14) Patch Tuesday round of Microsoft updates, the Microsoft Edge browser was still based on Chromium. Most of their discoverers were named, but we liked the one identified only as shares its open-source Chromium codebase with several other browsers, and not all had been updated yet at the time of this writing. The other flaws fixed included three in the Blink rendering engines that builds web pages in Chrome, and two in the ANGLE graphics engine. ![]() But most of the Chrome zero-days fixed in 2021 have involved highly resourced nation-state attackers - i.e., government spies - going after high-value targets, which can include political dissidents, foreign diplomats or others whose computers and smartphones might contain lots of valuable information. There's no information yet on who was using these two zero-days flaws, or who was being targeted. Without JavaScript and similar technologies, you wouldn't be able to open a Gmail message without reloading the entire page. Before JavaScript, websites were largely static. Given initial the grid with random states, the objective is to set all cells to off state. You can swap the state of any cell, but when you do so, the adjacent cells (horizontally or vertically) are swapped as well. JavaScript is one of the chief components that make interactive websites possible. Lights Out is a grid-based puzzle where each cell has two states: on/off. The second flaw is characterized as "use after free in Indexed DB API," meaning that hackers figured out a way to hijack running memory allocated to a programming interface that handles JavaScript interactions with a database. ![]() Google has patched half-a-dozen zero-days this year related to V8. The first is described as an "out-of-bounds write in V8," which is Chrome's JavaScript engine and handles many of the moving parts on a web page. They're called "zero days" because hackers were already using them in attacks before Chrome found out, giving the developers no time to prepare fixes before exploitation began. These are the first zero-days patched in Chrome since mid-July. ![]()
