Descriptions

A type confusion issue was addressed with improved memory handling. This issue is fixed in Safari 14.0. Processing maliciously crafted web content may lead to arbitrary code execution.

Se abordó un problema de confusión de tipo con un manejo de la memoria mejorado. Este problema es corregido en Safari versión 14.0. El procesamiento de contenido web creado maliciosamente puede conllevar a una ejecución de código arbitraria

This vulnerability allows remote attackers to execute arbitrary code on affected 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 optimization of calls to String.prototype.replace. By performing actions in JavaScript, an attacker can trigger a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process.
