CVE-2015-1641 is a remote code execution vulnerability in Microsoft Word and related Microsoft Office components caused by memory corruption when processing a specially crafted Rich Text Format (RTF) document. Affected products include Microsoft Word 2007 SP3, Office 2010 SP2, Word 2010 SP2, Word 2013 SP1, Word 2013 RT SP1, Word for Mac 2011, Office Compatibility Pack SP3, Word Automation Services on SharePoint Server 2010 SP2 and 2013 SP1, and Office Web Apps Server 2010 SP2 and 2013 SP1. Successful exploitation occurs when the vulnerable application parses the crafted RTF content, leading to corruption of process memory and allowing attacker-controlled code to run in the context of the application. The flaw has been widely used in spearphishing campaigns to deliver malware through weaponized Office documents.
