Summary
<p>An elevation of privilege vulnerability exists when the Windows Application Compatibility Client Library improperly handles registry operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.</p>
<p>To exploit the vulnerability, an attacker would first need code execution on a victim system. An attacker could then run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the Windows Application Compatibility Client Library properly handles registry operations.</p>
