An unspecified vulnerability in Microsoft Excel could allow an attacker to execute arbitrary code on a vulnerable system.
Microsoft Excel contains a vulnerability that could be exploited when Excel opens a specially crafted document. It is possible that the vulnerability can be exploited by opening a Microsoft Office document that includes an embedded Excel spreadsheet. Based on limited testing, Excel 2003, Excel Viewer 2003, Excel XP (2002), Excel 2000, Excel 97, Excel Viewer 97, and Excel 2004 for Mac OS appear to contain a buffer overflow vulnerability. Other versions of Excel may also be affected. Microsoft Security Advisory (921365) indicates that the vulnerability is related to Excel's repair mode.
By convincing a user to open a specially crafted Excel document, an attacker could execute arbitrary code with the privileges of the user running Excel. If the user is logged in with administrative privileges, the attacker could take complete control of a vulnerable system.
