CVE-2009-3129

CVSS 7.8 HIGHEPSS 85.7%● KEVCWE-787

In short

Microsoft Excel fails to properly validate the size of data in a specific record type when opening spreadsheets, allowing attackers to corrupt memory and run malicious code by sending a specially crafted Excel file.

Technical detail

A memory corruption vulnerability exists in Excel's FEATHEADER record parsing due to improper validation of the cbHdrData size element, leading to incorrect pointer offset calculation. Remote attackers can exploit this via a malicious spreadsheet to achieve arbitrary code execution with the privileges of the user opening the file.
