  "description": "\u003Cp\u003EA denial of service vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited the vulnerability could cause a target system to stop responding.\u003C/p\u003E\n\u003Cp\u003ETo exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application or to convince a user to open a specific file on a network share. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to cause a target system to stop responding.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting how Windows handles objects in memory.\u003C/p\u003E",
