An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 13.5 and iPadOS 13.5, macOS Catalina 10.15.5, tvOS 13.4.5, watchOS 6.2.5. Processing a maliciously crafted audio file may lead to arbitrary code execution.

Se abordó una lectura fuera de límites con una comprobación de límites mejorada. Este problema es corregido en iOS versión 13.5 y iPadOS versión 13.5, macOS Catalina versión 10.15.5, tvOS versión 13.4.5, watchOS versión 6.2.5. El procesamiento de un archivo de audio diseñado con fines maliciosos puede conllevar a una ejecución de código arbitraria

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the AudioToolboxCore module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
