Solution MS14-017
Vendor description Microsoft is aware of a vulnerability affecting supported 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. Applying the Microsoft Fix it solution, "Disable opening RTF content in Microsoft Word," prevents the exploitation of this issue through Microsoft Word.
SophosLabs comments Sophos products detect booby-trapped files as: Exp/20141761-A.
