Descriptions

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 13.6 and iPadOS 13.6, macOS Catalina 10.15.6, tvOS 13.4.8, watchOS 6.2.8, iTunes 12.10.8 for Windows, iCloud for Windows 11.3, iCloud for Windows 7.20. Processing a maliciously crafted image may lead to arbitrary code execution.

Se abordó un problema de escritura fuera de límites con una comprobación de límites mejorada. Este problema es corregido en iOS versión 13.6 y iPadOS versión 13.6, macOS Catalina versión 10.15.6, tvOS versión 13.4.8, watchOS versión 6.2.8, iTunes versión 12.10.8 para Windows, iCloud para Windows versión 11.3, iCloud para Windows versión 7.20. El procesamiento de una imagen creada maliciosamente puede conllevar a una ejecución de código arbitraria

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 ImageIO framework. Crafted data in a PIC image can trigger a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
