Scripting Engine Information Disclosure Vulnerability
An information disclosure vulnerability exists when VBScript improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the user’s computer or data.
Scripting Engine Memory Corruption Vulnerability
A remote code execution vulnerability exists in the way that the VBScript engine renders, when handling objects in memory in Internet Explorer. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.
