Apple has released a new supplemental update for macOS Catalina 10.15.7 that contains fixes for several security flaws that have been used in the wild.
The macOS 10.15.7 Supplemental Update, which Apple recommends all users download, can be acquired by heading into the Update menu in System Preferences.
According to Apple's security updates webpage, the macOS update patches three flaws discovered by Google's Project Zero team of bug hunters.
That includes a vulnerability that could allow maliciously crafted fonts to execute arbitrary code, as well as two kernel flaws that may allow malicious applications to execute code with kernel privileges and disclose kernel memory. Apple says it is aware of reports that exploits for all three security vulnerabilities have been discovered in the wild.
The Supplemental Update comes about one month after Apple released macOS 10.15.7, which contained a handful of bug fixes.

Unlike Windows, you can count on Apple to fix vulnerable security flaws to fix it sooner.
Always keep your system updated, no matter what the naysayers whine about how they have to stay where they are because of this or that. It just means they have borked systems to begin with.
My old iMac sat with the Apple Logo Progress Bar 1cm complete for about 30 minutes before continuing.
But, now it looks to have installed without an issue.
We have 3 Late 2012 MacMini's at home and not one of them can run Catalina. All our MacMini's slow to a crawl, video is rendered jerkily at no more than 15fps, and, finally, the killer is the Magic trackpad 2's (or any Apple mouse wired/less) and keyboard. Each and every click on the trackpad 2's or tap on a keyboard key hangs the entire system on each MacMini for 30-40 seconds....sometimes one can wait a full 10 minutes before control is handed back. We have upgraded the RAM to 16Gb (the max) in each Mini and fitted SSD's. Still, the problem is apparent. Apple Support keep telling us to carry out fresh installs of Catalina which each of us has done no fewer than 4 times and the Macs still respond with the speed of a slug. I updated back to Mojave and everything works just fine. Now we are all pissed off that Apple keep reminding us that an OS update (Catalina) is available when the truth is Catalina will not run on Late 2012 MacMini's. It's a dead-end. Anyone here managed to get Catalina running absolutely flawlessly on their 2012 MacMini?
