Subject: 
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (MS14-082)
Overview: 

Microsoft has released a patch that resolves one privately reported vulnerability in Microsoft Office. Microsoft Office is an office suite of desktop applications, servers and services for both Microsoft Windows and Apple's OS X operating systems.

Successful exploitation could result in the attacker gaining the same user rights as the current user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.

Systems Affected: 
  • Microsoft Office 2007
  • Microsoft Office 2010
  • Microsoft Office 2013

Description: 

The security update addresses the vulnerability by correcting how Microsoft Office parses specially crafted files and by helping to ensure that the Microsoft Common Controls (MSCOMCTL) library included with Microsoft Office software properly implements Address space layout randomization (ASLR).

Successful exploitation could result in the attacker gaining the same user rights as the current user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.

Actions: 

We recommend the following actions be taken:

  • Apply appropriate patch provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
