A denial of service vulnerability exists when Windows improperly handles objects in memory, aka 'Windows Denial of Service Vulnerability'.

A 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.
To 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.
The update addresses the vulnerability by correcting how Windows handles objects in memory.
