  "title": "Microsoft splwow64 Elevation of Privilege Vulnerability",
  "description": "\u003Cp\u003EA local elevation of privilege vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited the vulnerability could elevate privileges on an affected system from low-integrity to medium-integrity.\u003C/p\u003E\n\u003Cp\u003EThis vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted.\u003C/p\u003E\n\u003Cp\u003EThe security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls..\u003C/p\u003E",
