Un desbordamiento de búfer basado en pila en Microsoft Excel 2007 SP2 y SP3 y Server 2010 SP1, Office 2011 para Mac, Excel Viewer y Office Compatibility Pack SP2 y SP3 permite a atacantes remotos ejecutar código de su elección a través de una hoja de cálculo hecha a mano. Se trata de un problema también conocido como "vulnerabilidad de desbordamiento pila en Excel".
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft 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 Excel's parsing of Feature11/Feature12 records. The process trusts a supplied counter value without validating its size and proceeds to use it within a copy operation to the stack. An attacker can abuse this to execute arbitrary code under the context of the user running Excel.
