Microsoft fixes 55 flaws, 3 of them exploited by Russian cyberspies
Microsoft released security patches Tuesday for 55 vulnerabilities across the company's products, including for three flaws that are already exploited in targeted attacks by cyberespionage groups.
Fifteen of the vulnerabilities fixed in Microsoft's patch bundle for May are rated as critical and they affect Windows, Microsoft Office, Microsoft Edge, Internet Explorer, and the malware protection engine used in most of the company's anti-malware products.
System administrators should prioritize the Microsoft Office patches because they address two vulnerabilities that attackers have exploited in targeted attacks over the past two months. Both of these flaws, CVE-2017-0261 and CVE-2017-0262, stem from how Microsoft Office handles Encapsulated PostScript (EPS) image files and can lead to remote code execution on the underlying system.
