Executive Summary

A remote code execution vulnerability exists when Azure Stack fails to check the length of a buffer prior to copying memory to it. An attacker who successfully exploited this vulnerability could allow an unprivileged function run by the user to execute code in the context of NT AUTHORITY\system thereby escaping the Sandbox. The security update addresses the vulnerability by ensuring that Azure Stack sanitizes user inputs.
