Microsoft Excel 2007 SP3, Excel 2010 SP2, Excel 2013 SP1, Excel 2013 RT SP1, Excel 2016, Excel para Mac 2011, Excel 2016 para Mac, Office Compatibility Pack SP3, Excel Viewer y Excel Services en SharePoint Server 2007 SP3, 2010 SP2 y 2013 SP1 permiten a atacantes remotos ejecutar código arbitrario a través de un documento Office manipulado, 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 handling of binary (.xlsb) Excel files. By providing a malformed .xlsb file, an attacker can cause the target location for a branch to be read from uninitialized memory. An attacker could leverage this to execute arbitrary code under the context of the Excel process.
