Microsoft released a bevy of critical updates Tuesday, with a focus on the multitude of Excel vulnerabilities that have sprung up over recent months. Eight different flaws within the popular spreadsheet program were fixed in a single update, along with two critical flaws in Windows, two other critical issues affecting Office and other Microsoft programs, and "important" issues with the .NET Framework and IIS.
The Excel update includes fixes for various issues with malformed records and values, the most serious of which could open up a user's machine to a remote code execution risk. The patch also replaces a previous one issued in March to correct other issues within Excel.
