CVE-2018-6065

Desbordamiento de enteros en el cálculo del tamaño de asignación requerido al instanciar un nuevo objeto JavaScript en V8 en Google Chrome en versiones anteriores a la 65.0.3325.146 permitía que un atacante remoto pudiese explotar una corrupción de memoria dinámica (heap) mediante una página HTML manipulada.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Xiaomi Mi6 Browser. 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 the CalculateInstanceSizeHelper function. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Chrome V8 suffers from an integer overflow vulnerability in object allocation size.

Google Chromium V8 Engine contains an integer overflow vulnerability that allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.
