An elevation of privilege vulnerability exists in the way that the dnsrslvr.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
\nTo exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.
\nThe security update addresses the vulnerability by ensuring the dnsrslvr.dll properly handles objects in memory.
