Microsoft released patches for 51 vulnerabilities Tuesday, including one affecting Internet Explorer that hackers have exploited in targeted attacks against organizations in South Korea. The affected products include Windows, Internet Explorer, Microsoft Edge, Office and MicrosoftNET Framework. Microsoft patches were covered in 16 security bulletins, eight rated critical and eight important. The patches should be prioritized, but administrators might also want to pay immediate attention to some that Microsoft only rated important, such as the privilege escalation flaw in the handling of RPC requests.”]
