Vulnerabilidad de uso después de liberación de memoria en Microsoft Excel 2007 SP3, Excel 2010 SP2, Excel 2013 SP1, Excel 2013 RT SP1, Excel 2016, Excel para Mac 2011, Excel 2016 para Mac, Excel Viewer, Office Compatibility Pack SP3 y Excel Services en SharePoint Server 2007 SP3, 2010 SP2 y 2013 SP1 permite a atacantes remotos ejecutar código arbitrario a través de un elemento fileVersion largo en un documento Office, también conocida como 'Microsoft Office Memory Corruption Vulnerability'.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Excel. 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 the parsing of the fileVersion element in the workbook. By providing an overly long value, an attacker can force an object to be used after it has been freed. This could allow the attacker to execute arbitrary code under the context of the current process.
