Cybersecurity researchers have identified four security vulnerabilities in Microsoft Excel and Microsoft Office 365 that can be exploited to execute malicious code.
The vulnerabilities, reported by Check Point, come from the legacy code that stems from Excel95, giving them reason to believe that the vulnerabilities have existed for several years.
Check Point's team adds that the four vulnerabilities can be exploited through malicious Word, Excel, and Outlook documents. Patches for three of the vulnerabilities tracked as CVE-2021-31174, CVE-2021-31178, CVE-2021-31179 have already been issued by Microsoft. The fourth issue tracked as CVE-2021-31939 should be fixed in the June 2021 Patch Tuesday release.
