Se abordó un problema de desbordamiento de enteros con una comprobación de entradas mejorada. Este problema es corregido en tvOS versión 15.5, iTunes versión 12.12.4 para Windows, iOS versión 15.5 y iPadOS versión 15.5, watchOS versión 8.6, macOS Monterey versión 12.4. Un atacante remoto puede ser capaz de causar la terminación inesperada de la aplicación o una ejecución de código arbitrario

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. Interaction with the ImageIO library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of WebP images in the ImageIO framework. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before reading from memory. An attacker can leverage this vulnerability to execute code in the context of the current process.
