An information disclosure vulnerability exists when affected Microsoft browsers improperly handle objects in memory, aka "Microsoft Browser Information Disclosure Vulnerability." This affects Internet Explorer 11, Microsoft Edge.

Existe una vulnerabilidad de divulgación de información cuando los navegadores de Microsoft gestionan incorrectamente los objetos en la memoria. Esto también se conoce como "Microsoft Browser Information Disclosure Vulnerability". Esto afecta a Internet Explorer 11 y Microsoft Edge.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Microsoft Edge. 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 ImageData objects in WebGL. By performing actions in JavaScript an attacker can cause a pointer to be reused after it has been freed. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
