Apple Urges Immediate Device Upgrade to Address Three 'Active' Zero-Day Exploits

The security patch was deployed using Apple's new Rapid Security Response automatic update system


A security bulletin that was issued this week emphasizes the immediate installation of available iOS updates for Apple users. Reports state that this recommendation was prompted by the discovery of three zero-day exploits, all of which are currently being actively exploited on devices that have not been patched. In addition to addressing these exploits, the update also addresses more than 30 other vulnerabilities that were identified in the recent iOS 16.4 release.

Apple is urging iPhone and iPad users to promptly update to iOS 16.5 and iPadOS 16.5 in order to mitigate the risks associated with the three zero-day exploits. These vulnerabilities are specifically linked to the WebKit browser engine and encompass the following:

- CVE-2023-32409: Allows a remote attacker to break out of the Web Content security sandbox.

- CVE-2023-28204: May result in the disclosure of sensitive information when processing web content.

- CVE-2023-32373: Processing maliciously crafted web content may lead to arbitrary code execution.

The identified vulnerabilities significantly heighten the risk of unauthorized third parties gaining access to users' data and personal information. Moreover, these security loopholes can potentially enable malicious actors to execute arbitrary code, allowing them to run any command or code on a targeted machine or process.

Earlier this year, it was reported that Apple had surpassed the milestone of two billion active devices, underscoring the extensive scale of the issue faced by Apple. Given the nature of the vulnerabilities, the WebKit browser engine exploit could potentially impact a wide range of these two billion devices. The affected devices include:

- All iPad Pro models

- iPad Air (3rd generation and later)

- iPad 5th generation (and later)

- iPad Mini (5th generation and later)

- iPhone 6s and subsequent models

- Mac workstations and laptops running macOS, Big Sur, Monterey, and Ventura

- Apple Watch (Series 4 and later)

- Apple TV 4K and HD

Many users have already received automatic iOS updates through Apple's Rapid Security Response system. Although the deployment of these updates is typically based on geographic regions and dependent on connectivity, there may still be users whose phones and tablets are awaiting the automatic updates. Such users are strongly encouraged to manually update their devices to version 16.5. To do this, navigate to the Settings app, select General, and then choose Software Update. Tap on "Download and Install" and allow a few minutes for the process to complete.

It is also advisable to ensure that all other Apple devices are kept up to date. The process of updating is straightforward since the option to download updates manually can be found in the same location on all devices, namely under Settings > General > Software Update.

In conclusion, it is of utmost importance for Apple users to heed the security bulletin's advice and promptly install the available iOS updates. By addressing the identified vulnerabilities, including the three zero-day exploits, users can effectively mitigate the risks associated with unauthorized access to their data and potential arbitrary code execution. Keeping all Apple devices up to date is crucial for maintaining a secure digital environment. By staying vigilant and ensuring regular updates, users can enhance the overall security of their devices and protect their personal information.
