Remote code vulnerabilities exist in the way Excel: 1) processes data validation records when loading Excel files into memory; 2) handles data when importing files into Excel; 3) Style record data when opening Excel files; 4) handles malformed formulas; 5) handles rich text values when loading application data into memory; 6) handles conditional formatting values; and 7) handles macros when opening specially crafted Excel files. The risk is MEDIUM. An attacker could exploit the vulnerabilities by sending malformed files which could be hosted on a specially crafted or compromised Web site, or included as an e-mail attachment.
