Múltiples problemas de corrupción de memoria fueron abordados mejorando el manejo de la memoria. Este problema es corregido en iOS versión 12.3, macOS Mojave versión 10.14.5, tvOS versión 12.3, Safari versión 12.1.1, iTunes para Windows versión 12.9.5, iCloud para Windows versión 7.12. El procesamiento de contenido web diseñado maliciosamente puede conllevar a una ejecución de código arbitrario.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable 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 BreakingContext object. 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
