Descriptions

A memory corruption issue was addressed with improved state management. This issue is fixed in iOS 12.1.3, macOS Mojave 10.14.3. Processing maliciously crafted web content may lead to arbitrary code execution.

Se abordó un problema de corrupción de memoria con la mejora de la gestión de estados. Este problema se ha resuelto en iOS 12.1.3 y macOS Mojave 10.14.3. El procesamiento de contenido web maliciosamente manipulado puede conducir a la ejecución de código arbitrario.

This vulnerability allows remote attackers to execute arbitrary code 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 RTCPeerConnection objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process.
