A web application framework running on the remote host is affected by an information disclosure vulnerability.


The version of Silverlight 5 installed on the remote Windows host is missing security update KB4017094. It is, therefore, affected by an information disclosure vulnerability in the open-source libjpeg image processing library due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this to disclose sensitive information that can be utilized to bypass ASLR security protections.
