Descriptions

A memory corruption issue was addressed with improved state management. This issue is fixed in watchOS 9.3, tvOS 16.3, macOS Ventura 13.2, iOS 16.3 and iPadOS 16.3. Processing an image may lead to a denial-of-service.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. Interaction with the ImageIO framework is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the ImageIO framework. Crafted data in a KTX image can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
