\nReading Time: 1 Minute\nGoogle is warning that a bug in its Chrome web browser is actively under attack, and it is urging users to upgrade to the latest 91.0.4472.101 version to mitigate the issue.\nIn all, Google rolled out fixes for 14 bugs impacting its Windows, Mac and Linux browsers as part of its June update to the Chrome desktop browser.\n\n\u201cGoogle is aware that an exploit for CVE-2021-30551 exists in the wild,\u201d wrote Chrome technical program manager Prudhvikumar Bommana in a Wednesday post. That exploit is identified as a type confusion bug within Google\u2019s V8 open-source JavaScript and WebAssembly engine.\n\nThe confusion vulnerability is tied to the browser\u2019s ActionScript Virtual Machine. \u201cUsually, when a piece of code doesn\u2019t verify the type of object that is passed to it, and uses it blindly without type-checking, it leads to type confusion,\u201d according to a technical description of the bug. Possible Wider Impact of Exploited Chrome Browser BugThe update coincides with the release of the Android Chrome browser to Chrome 91 (91.0.4472.101), also on Wednesday. While the desktop and mobile versions of the Chrome web browser share the same version number, it is unclear if the updated Android Chrome browser is impacted by the same vulnerabilities.\n\nAlso unclear is if Microsoft\u2019s Edge browser, based on the Chromium open-source browser codebase (principally developed and maintained by Google), is also impacted.\nSee Also: RockYou2021: largest password compilation of all time leaked online \u2013 8.4 billion entries In related news, on Tuesday, Microsoft released a patch for vulnerabilities under active attack, including CVE-2021-33742, impacting its Edge browser. That bug is a remote-code execution\u00a0(RCE) vulnerability within the Edge browser\u2019s MSHTML component.\n\n\u201cThe MSHTML platform is used by Internet Explorer mode in Microsoft Edge as well as other applications through WebBrowser control,\u201d Microsoft explained. Critical Browser Cache Bug: CVE-2021-30544As part of the June Chrome update, Google patched a critical use-after-free bug (CVE-2021-30544) within the browser\u2019s optimization engine called BFCache. This browser component enables back-and-forward navigation between cached webpages within Chrome.\n\nAs customary with recently disclosed bugs, Google did not release the details tied to any of the vulnerabilities patched Wednesday. \u201cAccess to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third-party library that other projects similarly depend on, but haven\u2019t yet fixed,\u201d the Google advisory stated.\nSee Also: Offensive Security Tool: Pacu \u2013 The Amazon Web Services Exploitation Framework Google credits Rong Jian and Guang Gong of 360 Alpha Lab for finding the BFCache bug in May. For their bug hunting efforts, the pair earned $25,000.
