Un desbordamiento del búfer fue abordado mejorando la comprobación de límites. Este problema es corregido en macOS Catalina versión 10.15, tvOS versión 13, iTunes para Windows versión 12.10.1, iCloud para Windows versión 10.7, iCloud para Windows versión 7.14. El procesamiento de un archivo de texto diseñado maliciosamente puede conllevar a una ejecución de código arbitrario.

This vulnerability allows remote attackers to execute arbitrary code 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 CFFromShiftJISLen function. Crafted data in a DOC file can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
