CVE-2010-1900

Microsoft Office Word 2002 SP3, 2003 SP3, y 2007 SP2; Microsoft Office 2004 y 2008 para Mac; Open XML File Format Converter para Mac; Office Word Viewer; Office Compatibility Pack para Word, Excel, y PowerPoint 2007 File Formats SP2; y Works 9 no manejan adecuadamente los registros mal formados, lo que permite a atacantes remotos ejecutar código de su elección o causar una denegación de servicio (corrupción de memoria) a través de archivos manipulados, también conocido como "Word Record parsing Vulnerability."

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Word. User interaction is required to exploit this vulnerability in that the target must open a malicious document.
The specific flaw exists in the parsing of sprmCMajority records in a Word document. Due to the lack of parameter checking when processing sprmCMajority sprm groups it is possible to arbitrarily control the amount of data being written to a stack based buffer resulting in a stack overflow vulnerability which can overwrite critical exception structures. Successful exploitation can lead to remote code execution under the credentials of the currently logged in user.
