Hello and welcome to this month’s blog on the Microsoft patch releases. This month, Microsoft will release four bulletins that cover a total of 12 vulnerabilities.
Of those, 11 are rated ‘critical’ and one is rated ‘important’. Two of the critical issues affect Office Web Components and have the potential to be the worst of the bunch. Office Web Components are installed as part of multiple applications. The vulnerabilities affecting them can be triggered by simply visiting a web page with some attacker-controlled content. Seven of the critical issues affect Microsoft Excel and require a victim to open a malicious file to trigger the vulnerability. The remaining issues affect Outlook and Office.
Microsoft’s summary of the March releases can be found here:
