Buffer overflow in Microsoft Word in Office 2000 SP3, Office XP SP3, Office 2003 Sp1 and SP2, and Microsoft Works Suites through 2006, allows user-assisted attackers to execute arbitrary code via a malformed object pointer, as originally reported by ISC on 20060519 for a zero-day attack.

Microsoft Office Excel contains a remote code execution vulnerability that can be exploited when a specially crafted Excel file is opened. This malicious file could be delivered as an email attachment or hosted on a malicious website. An attacker could leverage this vulnerability by creating a specially crafted Excel file, which, when opened, allowing an attacker to execute remote code on the affected system.

Microsoft Office contains a buffer overflow vulnerability that allows remote attackers to execute code via a Word document with a crafted tag containing an invalid length field.

Excel in Microsoft Office 2000 SP3, Office XP SP3, Office 2003 SP3, and Office 2004 and 2008 for Mac; Excel in 2007 Microsoft Office System SP1 and SP2; Open XML File Format Converter for Mac; Microsoft Office Excel Viewer 2003 SP3; Microsoft Office Excel Viewer; and Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP1 and SP2 allow remote attackers to execute arbitrary code via a crafted Excel file with a malformed record object, aka "Object Record Corruption Vulnerability."

A stack-based buffer overflow vulnerability exists in the parsing of RTF data in Microsoft Office and earlier allows an attacker to perform remote code execution.
