Microsoft: Scripting Engine Security Feature Bypass Vulnerability


A security feature bypass vulnerability exists in Microsoft Edge as a result of how memory is accessed in code compiled by the Edge Just-In-Time (JIT) compiler that allows Arbitrary Code Guard (ACG) to be bypassed. By itself, this ACG bypass vulnerability does not allow arbitrary code execution. However, an attacker could use the ACG bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.
