Remote Code Execution in Microsoft Word via Crafted RTF Data
CVE-2014-1761 is a memory-corruption vulnerability in Microsoft Word and related Office components triggered by opening or processing specially crafted Rich Text Format (RTF) content. Affected products include Microsoft Word 2003 SP3, 2007 SP3, 2010 SP1/SP2, 2013, and 2013 RT; Word Viewer; Office Compatibility Pack SP3; Office for Mac 2011; Word Automation Services on SharePoint Server 2010 SP1/SP2 and 2013; Office Web Apps 2010 SP1/SP2; and Office Web Apps Server 2013. The flaw allows a remote attacker to supply malicious RTF data that causes memory corruption during document parsing, which can result in arbitrary code execution or denial of service. The vulnerability was exploited in the wild as a zero-day in March 2014 and was widely used in spearphishing campaigns by multiple threat actors.
