CVE-2016-3247

Microsoft Internet Explorer 11 y Microsoft Edge permiten a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, vulnerabilidad también conocida como "Microsoft Browser Memory Corruption Vulnerability".

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 processing of the CSS white-space property. By manipulating a document's elements an attacker can trigger a read past the end of an allocated buffer. An attacker could leverage this vulnerability to disclose information under the context of the current process.

A specially crafted web-page can cause an integer underflow in Microsoft Edge. This causes CTextExtractor::GetBlockText to read data outside of the bounds of a memory block.
