Microsoft's Excel application contains a vulnerability that could allow a remote attacker to gain access to a system.
The flaw affects multiple versions of the spreadsheet software, including Excel 2000, 2002 and 2003, as well as versions of Microsoft Office containing those versions. It can also be manipulated in Excel Viewer 2003 and Office 2004 for Mac.
"Secunia Research has discovered a vulnerability in Microsoft Excel which can be exploited by malicious people to compromise a user's system," the security website said.
The vulnerability is caused by an error that occurs when validating an index value in the 'rtWnDesk' record. This can be exploited to corrupt memory via a specially crafted Excel Workspace file.
