![]() ![]() Apple is actively developing iOS 16, iPadOS 16, and macOS Ventura, and those updates are due out later this fall. We've contacted Apple to see whether it plans to release these patches for these older OSes, or if they aren't affected by the bugs and don't need to be patched.Īpple's software release notes for the updates don't reference any other fixes or features. WebKit is used in the Safari browser as well as in apps like Mail that use Apple's WebViews to render and display content.Īpple didn't release equivalent security patches for macOS Catalina or Big Sur, two older versions of macOS that are still receiving regular security updates. The other, CVE-2022-32893, is a WebKit bug that allows for arbitrary code execution via "maliciously crafted web content." Both discoveries are attributed to an anonymous security researcher. One, labeled CVE-2022-32894, is a kernel vulnerability that can allow apps "to execute arbitrary code with kernel privileges. iMac11,x (systems with AMD Radeon HD 5xxx and 6xxx series.Minimum OS: macOS 10. The three updates all fix the same pair of bugs. When installing, ensure your system is plugged in to power, or the update will not be installed. It can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012. Original story: Apple has released a trio of operating system updates to patch security vulnerabilities that it says "may have been actively exploited." The macOS 12.5.1, iOS 15.6.1, and iPadOS 15.6.1 updates are available for download now and should be installed as soon as possible. macOS Catalina Patcher lets you install macOS Catalina on Mac computers that are no longer officially supported. Still no word on whether the kernel vulnerability is present in either of these older operating systems, but we'll update if Apple responds to our query. ![]() ![]() ![]() 18, 3:45 p.m.: Apple has released the Safari 15.6.1 update for macOS Big Sur and Catalina to patch the WebKit vulnerability it fixed in macOS Monterey yesterday. I would also not use this if this is your only computer and you do not have a robust backup strategy in place.Update, Aug. Obviously, you should not use this in a trusted environment, e.g. It is not exactly clear whether the methods used to force macOS to boot have no consequences at all on system and data integrity, given that macOS itself consists of many closed-sourced parts and that Apple may make changes that could add unknown behaviour to hardware they do not support.ĭirect security implications are unknown as frou already pointed out, mostly due to the fact that this method of installing macOS will unlikely get the attention of security researchers (or hackers). They are maintained by a few persons (who may or may not have sufficient expertise, I do not know) and are probably not verified by many others with expertise. The Catalina patchers are partially closed-sourced in as far they do not use shell scripts. I have not been able to test it yet, but in Mojave and Catalina disabling SIP may also affect the Hardened Runtime that adds a whole range of run-time protections to third-party apps, including the same run-time protections and code-signing enforcements. SIP encompasses read-only access to system components (especially binaries) and run-time protections against debugging of and code injection into system processes as well unsigned kernel extensions. ![]()
