An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the TeamViewer service. 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 array. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of SYSTEM.

Un atacante debe obtener primero la capacidad de ejecutar c\u00f3digo con pocos privilegios en el sistema objetivo para poder explotar esta vulnerabilidad. El fallo espec\u00edfico se presenta en el servicio TeamViewer. El problema es debido a que no son comprobados apropiadamente los datos suministrados por el usuario, lo que puede resultar en una lectura m\u00e1s all\u00e1 del final de una matriz asignada.
