Vulnerability Information

VBScript Memory Corruption Vulnerability - CVE-2014-6363

A remote code execution vulnerability exists in the way that the
VBScript engine, when rendered in Internet Explorer, handles objects in
memory. In a web-based attack scenario, an attacker could host a
specially crafted website that is designed to exploit this
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 this
vulnerability.
