-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Reference: CERT-EU Security Advisory 2014-032 Title: Vulnerability in Microsoft Word could allow remote code execution Version history: 11.03.2014 Initial publication Summary ======= There is a vulnerability affecting multiple versions of Microsoft Word. At this time, we are aware of limited, targeted attacks directed at Microsoft Word 2010. The vulnerability could allow remote code execution if a user opens a specially crafted RTF file using an affected version of Microsoft Word, or previews or opens a specially crafted RTF email message in Microsoft Outlook while using Microsoft Word as the email viewer. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. The vulnerability is a remote code execution vulnerability. The issue is caused when Microsoft Word parses specially crafted RTF-formatted data causing system memory to become corrupted in such a way that an attacker could execute arbitrary code. The vulnerability could be exploited through Microsoft Outlook only when using Microsoft Word as the email viewer. Note that by default, Microsoft Word is the email reader in Microsoft Outlook 2007, Microsoft Outlook 2010, and Microsoft Outlook 2013. CVE-2014-1761 Vulnerable systems ================== Microsoft Word 2003 Microsoft Word 2007 Microsoft Word 2010 Microsoft Word 2013 What can you do? ================ Applying the Microsoft Fix it solution, "Disable opening RTF content in Microsoft Word," prevents the exploitation of this issue through Microsoft Word. [3] Deploy the Enhanced Mitigation Experience Toolkit, EMET helps mitigate the exploitation of this vulnerability by adding additional protection layers that make the vulnerability harder to exploit. EMET 4.1, in the recommended configuration, is automatically configured to help protect affected software installed on your system. No additional steps are required.
