<p>An elevation of privilege vulnerability exists when the .NET Framework common language runtime (CLR) allows file creation in arbitrary locations. An attacker who successfully exploited this vulnerability could write files to folders that require higher privileges than what the attacker already has.</p> <p>To exploit the vulnerability, an attacker would need to log into a system. The attacker could then specify the targeted folder and trigger an affected process to run.</p> <p>The update addresses the vulnerability correcting how the .NET Framework CLR process logs data.</p>
