The remote Windows host is missing a security update. It is, therefore, affected by an information disclosure vulnerability in the Windows Common Log File System (CLFS) due to improper handling of objects in memory. A local attacker can exploit this vulnerability, via a specially crafted application, to bypass security measures and disclose sensitive information.
