BleepingComputer.com: Microsoft Excel Vulnerability

US-CERT advises today (5/16/06) that there is an unpatched Excel vulnerability that could allow a hacker to gain access to and control of a computer..."by convincing a user to open a specially crafted Excel document. The Excel document could be included as an email attachment or hosted on a web site. It may also be possible to exploit the vulnerability using Excel documents embedded in other Office documents."

Until a patch is released, the agency recommends extreme caution in opening "...unfamiliar or unexpected Excel or other Office documents, including those received as email attachments or hosted on a web site."

John
