Descriptions
The Microsoft (1) VBScript 5.7 and 5.8 and (2) JScript 5.7 and 5.8 engines, as used in Internet Explorer 8 through 11 and other products, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted Filter arguments, aka "Scripting Engine Memory Corruption Vulnerability."
Los motores Microsoft (1) VBScript 5.7 y 5.8 y (2) JScript 5.7 y 5.8, tal como se utiliza en Internet Explorer 8 hasta la versión 11 y otros productos, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de argumentos Filter manipulados, también conocido como 'Scripting Engine Memory Corruption Vulnerability'.
This vulnerability allows remote attackers to execute arbitrary code in applications using the VBScript scripting language running on vulnerable installations of Microsoft Windows. Microsoft Internet Explorer is an affected application. 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 Join function in VBScript. By passing unexpected arguments to this function, an attacker can cause an integer to be incorrectly interpreted as a pointer to an object in memory. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current process.
