<p>An elevation of privilege vulnerability exists in Windows Audio Service when a malformed parameter is processed. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges when used in conjunction with another vulnerability.</p> <p>To exploit the vulnerability, an attacker could run a specially crafted application locally. This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.</p> <p>The update addresses the vulnerability by correcting how the Windows Audio Service handles these parameters.</p>
