Jun 9, 2021 Check Point Research (CPR) is urging Windows users to update their software, after discovering four security vulnerabilities that affect products in Microsoft Office suite, including Excel and Office online. Rooted from legacy code, the vulnerabilities could have granted an attacker the ability to execute code on targets via malicious Office documents, such as Word, Excel and Outlook. * Malicious code could have been delivered via Word documents (.DOCX) , Outlook Email (.EML) and most office file formats. * Vulnerabilities are the result of parsing mistakes made in legacy code, leading CPR to believe security flaws have existed for years. * CPR responsibly disclosed to Microsoft, who then issued fixes: CVE-2021-31174, CVE-2021-31178, CVE-2021-31179, CVE-2021-31939.
