iOS 18.3.2 includes several updates beyond the fix for streaming playback issues. Here are the key details:
1. Security Updates: The most critical aspect of this update is its security patches. iOS 18.3.2 addresses a significant vulnerability in WebKit, the engine powering Safari. This vulnerability, designated as CVE-5-01, could allow malicious web content to escape the Web Content sandbox, potentially enabling unauthorized access to device data. Apple strongly recommends updating to iOS 18.3.2 to prevent exploitation of this vulnerability, which is reportedly being used in sophisticated attacks[1][3][7].
2. Bug Fixes: In addition to security updates, iOS 18.3.2 includes important bug fixes. These are not detailed extensively in Apple's release notes, but they are intended to enhance the overall stability and performance of the iPhone[2][5].
3. General Improvements: While not explicitly listed, updates like iOS 18.3.2 often include minor tweaks to improve user experience and system reliability. These might not be as noticeable as major feature updates but contribute to a smoother operation of the device[3][5].
4. WebKit Sandbox Stability: The update reinforces the stability of the WebKit sandbox, ensuring that web content remains isolated and cannot access sensitive device resources. This is crucial for maintaining the security of the device and preventing unauthorized operations[3][7].
Overall, iOS 18.3.2 is primarily focused on addressing critical security vulnerabilities and enhancing system stability rather than introducing new features.
