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.
