Tech giant Apple released multiple security upgrades yesterday for its iOS, watchOS, tvOS, and macOS systems, addressing dozens of security bugs across its devices. The iOS update fixes 41 security flaws, including some that could potentially allow a remote attacker to execute malicious code on an Apple mobile device.
The update seems to be well-timed, as most of the world is still reeling from the latest ransomeware pandemic that has been racing across the globe since late last week. While the ransomeware attack targets Windows systems, Mac users are likely to feel a little safer knowing they have the most recent security patches installed.
Apple attributed almost half of the bug discoveries to Project Zero, Google’s internal security and bug-hunting initiative. The most significant patch Apple released yesterday is for the macOS. The update includes several fixes to the operating systems kernel, some of which address security vulnerabilities that would allow an application to gain access to kernel privileges as well as execute arbitrary code with kernel privileges.
The iBooks application received several fixes for bugs that would have, among other things, allowed a maliciously crafted book to open Web sites on its own without user permission. Meanwhile SQLite, a relational database management system, received four separate patches for issues that could have given an attacker remote access to a user’s device.
Apple’s mobile operating system, iOS, also received a major security upgrade. Several of the fixes relate to similar problems as those addressed in the macOS patch, such as the SQLite vulnerabilities, and kernel and iBooks bugs. Another major component of the OS that was patched was WebKit, a component that helps power the Safari browser.
The watchOS update includes improvements and bug fixes while the tvOS update provides bug fixes and…
