Pattern_F

The issue concerns a permissions problem within the SharedFileList component of macOS. Exploitation may allow an attacker to bypass existing security restrictions and elevate their privileges. An application may be able to escape its sandbox.

The issue was addressed with improved memory handling. An attacker may be able to cause unexpected app termination or arbitrary code execution.

A use-after-free issue was addressed with improved memory management, allowing an app to potentially execute arbitrary code with kernel privileges.

Name of the Vulnerable Software and Affected Versions: iOS versions prior to 14.5 iPadOS versions prior to 14.5 Description: The issue is related to an out-of-bounds read that has been addressed with improved input validation. A local user may be able to read kernel memory. Recommendations: For iOS versions prior to 14.5, update to iOS 14.5 or later. For iPadOS versions prior to 14.5, update to iPadOS 14.5 or later.

Name of the Vulnerable Software and Affected Versions: iOS versions prior to 14.5 iPadOS versions prior to 14.5 Description: A logic issue was addressed with improved state management, allowing an application to potentially execute arbitrary code with kernel privileges. Recommendations: For iOS versions prior to 14.5, update to iOS 14.5 or later to resolve the issue. For iPadOS versions prior to 14.5, update to iPadOS 14.5 or later to resolve the issue.

A memory corruption issue was addressed with improved input validation, allowing an application to potentially execute arbitrary code with kernel privileges.

The issue involves multiple out-of-bounds write problems that have been resolved through enhanced bounds checking. A malicious application could potentially execute arbitrary code with kernel privileges.

A logic issue was addressed with improved state management, which may allow an application to execute arbitrary code with kernel privileges.

A local attacker may be able to elevate their privileges due to a memory corruption issue. This issue was addressed with improved validation.
