Descriptions

Trend Micro Antivirus for Mac 2021 (Consumer) is vulnerable to a memory exhaustion vulnerability that could lead to disabling all the scanning functionality within the application. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability - i.e. the attacker must already have access to the target system (either legitimately or via another exploit).

Trend Micro Antivirus para Mac 2021 (Consumer) es susceptible a una vulnerabilidad de agotamiento de la memoria que podría conllevar a deshabilitar todas las funciones de escaneo dentro de la aplicación. Tenga en cuenta: un atacante primero debe obtener la capacidad de ejecutar código poco privilegiado en el sistema objetivo a los fines de explotar esta vulnerabilidad, es decir, el atacante ya debe tener acceso al sistema objetivo (ya sea legítimamente o mediante otro explotación)

This vulnerability allows local attackers to create a denial-of-service condition on affected installations of Trend Micro Antivirus for Mac. 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 iCoreService executable. The issue results from the lack of proper validation of user-supplied data, which can result in a memory exhaustion condition. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
