Microsoft Fixes 11 Critical, 39 Important Vulns

Another month, another Patch Tuesday update. Microsoft today released 50 security fixes for problems in ChakraCore, Hyper-V Server, Windows, Microsoft Office, and Office Services. Of these, 11 are rated as Critical severity and 39 are ranked Important. None of the bugs were under active attack at the time fixes were released, though one was publicly known.

Microsoft also released updates for Speculative Store Bypass, otherwise known as Spectre Variant 4, discovered in May. Today’s patches provide Windows support for Speculative Store Bypass Disable (SSBD) for Intel processors but require microcode/firmware and registry updates to fully protect against Variant 4.
