Microsoft Word Memory Corruption Vulnerability
Microsoft · Word
Summary
A memory corruption flaw in Microsoft Word, present across multiple Word versions (including 2003 through 2013 and Word Viewer, among others), arises from improper bounds handling in how the software processes RTF data. An attacker can craft a malicious RTF document that, when opened by a user, can execute arbitrary code or cause a denial of service, requiring user interaction to trigger.
Official description · NVD
Microsoft Word 2003 SP3, 2007 SP3, 2010 SP1 and SP2, 2013, and 2013 RT; Word Viewer; Office Compatibility Pack SP3; Office for Mac 2011; Word Automation Services on SharePoint Server 2010 SP1 and SP2 and 2013; Office Web Apps 2010 SP1 and SP2; and Office Web Apps Server 2013 allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted RTF data, as exploited in the wild in March 2014.
