Synopsis

The remote Windows host is affected by multiple remote code execution vulnerabilities.

Description

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

- A remote code execution vulnerability exists in Windows Text Services due to improper handling of objects in memory. A remote attacker can exploit this vulnerability by convincing a user to visit a specially crafted website or open a specially crafted file, resulting in the execution of arbitrary code. (CVE-2015-0059)

- A remote code execution vulnerability exists due to improper loading of DLL files. A remote attacker can exploit this vulnerability by convincing a user to visit a specially crafted website or remote network share, resulting in the execution of arbitrary code. (CVE-2015-0096) (EASYHOOKUP)

EASYHOOKUP is one of multiple Equation Group vulnerabilities and exploits disclosed on 2017/04/14 by a group known as the Shadow Brokers.

Solution

Microsoft has released a set of patches for Windows 2003, Vista, 2008, 7, 2008 R2, 8, 2012, 8.1, and 2012 R2.
