Descriptions

Microsoft Office Excel 2000 through 2004 allows user-assisted attackers to execute arbitrary code via malformed cell comments, which lead to modification of "critical data offsets" during the rebuilding process.

Microsoft Office Excel 2000 hasta la versión 2004 permite a atacantes asistidos por el usuario ejecutar código arbitrario a través de comentarios de celdas mal formadas, lo que conduce a modificación de "desplazamiento de datos críticos" durante el proceso de reconstrucción.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office. Exploitation requires that the attacker coerce the target into opening a malicious .XLS file.
The specific flaw exists within the rebuilding of malformed cell comments. When Excel encounters a malformed record it attempts to rebuild the broken meta-data. A flaw in this rebuilding process allows the user to specify critical data offsets eventually leading to code execution with the credentials of the current user.
