CVE-2016-0024
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Chakra JavaScript engine in Microsoft Edge allows remote attackers to execute arbitrary code via unspecified vectors, aka "Scripting Engine Memory Corruption Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA memory corruption vulnerability in the Chakra JavaScript engine in Microsoft Edge allows remote attackers to execute arbitrary code by exploiting unspecified vectors. The vulnerability stems from improper memory handling in the scripting engine, enabling an attacker to inject and execute malicious code on the victim's machine.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Microsoft Edge is installedOpen Start menu, search for 'Microsoft Edge' or check C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe (or C:\Program Files\Microsoft\Edge\Application\msedge.exe for ARM64)Affected if Microsoft Edge is not found on the system, the system is not affected by this specific Edge vulnerability
-
Check the installed Microsoft Edge versionLaunch Edge, go to Settings > About Microsoft Edge, or navigate to edge://settings/help in the address barAffected if All versions of Microsoft Edge prior to the MS16-006 patch are affected; the version alone does not confirm vulnerability status - patch status is the determining factor
-
Verify if security update MS16-006 is installedOpen Control Panel > Programs and Features > View installed updates, or run 'Get-HotFix -Description "Security Update" | Where-Object {$_.HotFixID -eq "KB3124266"}' in PowerShell (KB3124266 corresponds to MS16-006)Affected if If KB3124266 or a later cumulative update is NOT listed among installed updates, the system is likely vulnerable
-
Check Windows Update history for cumulative security patchesOpen Settings > Update & Security > Windows Update > View update history, or run 'Get-WmiObject -Class Win32_QuickFixEngineering | Select-Object HotFixID, InstalledOn | Sort-Object InstalledOn -Descending' in PowerShellAffected if If no recent Edge-related security updates (post-January 2016) appear in the update history, the Chakra vulnerability remains unpatched
-
Determine if the Chakra JavaScript engine is actively usedOpen Edge and navigate to any JavaScript-heavy website, or open Task Manager to confirm msedge.exe is running with JavaScript execution capabilityAffected if If Microsoft Edge is actively used and steps 3-4 show no applicable security updates installed, the system is vulnerable to the Chakra memory corruption exploit
A user is affected if Microsoft Edge is installed and the system is missing security update MS16-006 or subsequent cumulative updates that address the Chakra JavaScript engine memory corruption flaw.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the relevant Microsoft security update (MS16-006 or subsequent cumulative update) to patch the Chakra vulnerability in Microsoft Edge. Ensure browsers are updated through Windows Update or enterprise patch management systems.
