A remote code execution vulnerability exists within Microsoft Excel which may allow for a remote attacker to execute arbitrary code under the context of the logged in user. This vulnerability requires user interaction. In a web-based scenario (e-mail, Web site), a user would still have to open a file manually, as it would not be auto-opened.
NOTE: This information is gathered from the referenced Microsoft Advisory (947563). eEye Research is currently searching for an exploit sample to investigate the vulnerability further and will update this entry soon thereafter.
