  "description": "\u003Cp\u003EAn elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC).\u003C/p\u003E\n\u003Cp\u003EAn attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\u003C/p\u003E\n\u003Cp\u003ETo exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control over an affected system.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting how Windows handles calls to ALPC.\u003C/p\u003E",
