iOS 15.3 Update: Numerous Security Vulnerabilities Patched, Enhancing Device Protection. Should iFans Update?

Apple recently rolled out iOS 15.3 on January 26th, addressing lingering issues from the previous iOS 15.2 update for all supported iPhone users. What's new in iOS 15.3? Which phones can update to iOS 15.3? Should users upgrade to iOS 15.3? Let's delve into it.

Wondering about the new features in iOS 15.3? Should you make the jump to iOS 15.3? Let's explore.

First off, let's take a look at the issues Apple has addressed in the latest iOS 15.3 update:

1. Safari Bug Fix

iOS 15.3 brings no significant major changes; this update primarily addresses the critical security vulnerability in the Safari browser. Specifically, when accessing websites containing malicious code, users are at risk of exposing their browsing history and having their Google account information stolen.

This malicious code is related to a Javascript IndexedDB programming function, which stores information about the URLs users have visited and their Google login information.

Updating to the latest iOS is crucial, especially if you're using Chrome, to promptly fix this dangerous vulnerability. Otherwise, you risk exposing personal information and financial loss because Chrome on iOS 15.2 remains vulnerable. Additionally, if you're using a Mac, you'll need to upgrade to macOS 12.2, which addresses Safari bugs similarly. So, if you're wondering whether to update to iOS 15.3, the answer is definitely 'yes.'

2. Fixing IOMobileFrameBuffer Vulnerability

iOS 15.3 also fixes a memory-related vulnerability that could allow malicious apps to execute arbitrary code with admin privileges. This security flaw could easily lead hackers to steal your information as they have admin privileges to access the system.

Apple states that this vulnerability may have been exploited multiple times, meaning many hackers have discovered and used it, potentially affecting some iOS users.

3. Fixing Thumbnails Issue with HomeKit Camera:

iOS 15.3 addresses the problem of HomeKit Camera thumbnails not refreshing for some users within the Home app.

Thumbnails for HomeKit Secure Video cameras added to the Home app provide a way to review recent footage, and typically, these thumbnails will refresh automatically at intervals. In recent weeks, some users have been unable to refresh the thumbnails, but this issue appears to have been resolved by Apple in iOS 15.3.

4. Various Enhancements and Minor Bug Fixes

iOS 15.3 update also addresses several other vulnerabilities with ColorSync, Crash Reporter, iCloud, and Kernel, but none of these issues are known to have been heavily exploited by hackers.

When a patched vulnerability is heavily exploited by hackers, Apple notifies users, but that's not the case with these issues. The only heavily exploited vulnerability known is the IOMobileFrameBuffer bug mentioned earlier.

You can find detailed information about all the fixes in iOS 15.3 in Apple's security support documentation.

Should You Update to iOS 15.3? iPhones That Can Update to iOS 15.3

The iOS 15.3 update released will address some lingering issues from the previous version, preventing users from being affected by unfortunate incidents if attacked by security vulnerabilities that could expose their personal information for malicious purposes.

So if you're using iOS 15, I suggest updating to iOS 15.3 immediately for the best user experience. This upgrade is meant to fix minor bugs, so all devices on iOS 15.2 will be upgraded to iOS 15.3.
