Descriptions

Use-after-free vulnerability in Microsoft Word 2007 SP3, Office 2010 SP2, Word 2010 SP2, Word 2013 SP1, Word 2013 RT SP1, Word Viewer, 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 allows remote attackers to execute arbitrary code via a crafted Office document, aka "Microsoft Office Component Use After Free Vulnerability."

Vulnerabilidad de uso después de liberación en Microsoft Word 2007 SP3, Office 2010 SP2, Word 2010 SP2, Word 2013 SP1, Word 2013 RT SP1, Word Viewer, Office Compatibility Pack SP3, Word Automation Services on SharePoint Server 2010 SP2 y 2013 SP1, y Office Web Apps Server 2010 SP2 y 2013 SP1 permite a atacantes remotos ejecutar código arbitrario a través de un documento de Office manipulado, también conocido como 'vulnerabilidad de uso después de liberación en componentes de Microsoft Office.'

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Word. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within processing of abstract number elements in numbering.xml. By adding unexpected nodes within an abstractNum node, the attacker can cause memory to be used after it is freed, leading to arbitrary code execution in the context of the Word process.
