Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists in VBScript due to the improper disclosure of memory contents. An attacker can exploit this to gain information that can be used to further compromise a user's computer or data. (CVE-2015-6135)

- A remote code execution vulnerability exists related to the way the VBScript engine renders when handling objects in memory in Internet Explorer. A remote attacker can exploit this, via a crafted web page, document, or application, to gain elevated privileges and take full control of an affected system.
(CVE-2015-6136)

Solution

Microsoft has released a set of patches for Vista, 2008, and 2008 R2.
