Microsoft Edge JavaScript shift Method Uninitialized Memory Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Edge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the implementation of the JavaScript Array.shift method. By performing certain operations in script, an attacker can cause JavaScript to read uninitialized data from a memory location on the stack. An attacker can leverage this to execute code under the context of the current process.
