Microsoft Edge 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 Control Flow Guard CFG to be bypassed. By itself, this CFG bypass vulnerability does not allow arbitrary code execution. Howeve...

CVE-2017-5121
CVE-2017-5121 concerns the Chromium/Google Chrome V8 component. Reports in the connected sources confirm an out-of-bounds memory access in V8 before version 61.0.3163.100, enabling a remote attacker to execute arbitrary code within the Chrome sandbox on Linux, Windows, and Mac via a crafted page....
Microsoft Edge Scripting Engine Remote Memory Corruption Vulnerability(CVE-2017-11802)
No description provided by source. The "String.prototype.replace" method can be inlined in the JIT process. So in the method, all the calls which may break the JIT assumptions must be invoked with updating "ImplicitCallFlags". But "RegexHelper::StringReplace" calls the replace function without...
