Stack-based buffer overflow in Microsoft Excel 2002 SP3, 2003 SP3, and 2007 SP2; Office 2004 for Mac; Excel Viewer SP2; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2 allows remote attackers to execute arbitrary code via vectors related to an axis properties record, and improper incrementing of an array index, aka "Excel Array Indexing Vulnerability." Desbordamiento de búfer basado en pila en Microsoft Office Excel permite a atacantes remotos ejecutar código de su elección a través de vectores relacionados con un registro de propiedades de eje, y el incremento indebido de un índice de matriz. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office. 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 application's usage of a specific field used for incrementing an index used in an array. Due to the application failing to verify the usage of the index into the array, the application will copy the contents of the specified element into a statically sized buffer on the stack. • https://www.exploit-db.com/exploits/17227 http://dvlabs.tippingpoint.com/blog/2011/02/07/zdi-disclosure-microsoft http://secunia.com/advisories/39122 http://secunia.com/advisories/43232 http://securityreason.com/securityalert/8231 http://www.securitytracker.com/id?1025337 http://www.us-cert.gov/cas/techalerts/TA11-102A.html http://www.vupen.com/english/advisories/2011/0940 http://zerodayinitiative.com/advisories/ZDI-11-042 https://docs.microsoft.com/en-us/security-updates/securityb • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Microsoft Excel 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; and Excel Viewer SP2 do not properly handle errors during the parsing of Office Art records in Excel spreadsheets, which allows remote attackers to execute arbitrary code via a malformed object record, related to a "stray reference," aka "Excel Linked List Corruption Vulnerability." Excel 2002 SP3, 2003 SP3, 2007 SP2 y 2010; Office 2004, 2008 y 2011 para Mac; Open XML File Format Converter para Mac; y Excel Viewer SP2 de Microsoft, no maneja apropiadamente los errores durante el análisis de registros Art de Office en hojas de cálculo de Excel, lo que permite a los atacantes remotos ejecutar código arbitrario por medio de un registro de objeto malformado, relacionado con una "stray reference", también se conoce como "Excel Linked List 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 way the application parses an Office Art record within a Microsoft Excel Document. Specifically, when parsing an office art object record, if an error occurs, the application will add a stray reference to an element which is part of a linked list. • http://dvlabs.tippingpoint.com/blog/2011/02/07/zdi-disclosure-microsoft http://osvdb.org/70904 http://secunia.com/advisories/39122 http://secunia.com/advisories/43231 http://www.securitytracker.com/id?1025337 http://www.us-cert.gov/cas/techalerts/TA11-102A.html http://www.vupen.com/english/advisories/2011/0940 http://zerodayinitiative.com/advisories/ZDI-11-041 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2011/ms11-021 https://oval.cisecurity.org/repository&#x • CWE-20: Improper Input Validation •
