Multiple memory corruption issues were addressed with improved memory handling. This issue affected versions prior to iOS 12, tvOS 12, watchOS 5, Safari 12, iTunes 12.9 for Windows, iCloud for Windows 7.7.

Se abordaron múltiples problemas de corrupción de memoria con una gestión de memoria mejorada. El problema afectaba a iOS en versiones anteriores a la 12, tvOS en versiones anteriores a la 12, watchOS en versiones anteriores a la 5, Safari en versiones anteriores a la 12, iTunes para Windows en versiones anteriores a la 12.9 y iCloud para Windows en versiones anteriores a la 7.7.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Apple Safari. 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 handling of Arrays. By performing actions in JavaScript, an attacker can trigger access to memory prior to initialization. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
