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 a crafted replace operation with a JavaScript regular expression, 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, permiten a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de una operación de sustitución manipulada con una expresión regular JavaScript, también conocido como 'Scripting Engine Memory Corruption Vulnerability'.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The vulnerability relates to search and replace operations performed using JavaScript regular expressions. An attacker can cause the in-memory representation of a regular expression to be freed while it is being used in a replace operation. An attacker can leverage this vulnerability to execute code under the context of the current process.
Recompiling the regular expression pattern during a replace in JScript version 5.7 (MSIE 8) can cause the code to reuse a freed string, but only if the string is freed from the cache by allocating and freeing a number of strings of certain size.
