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 · unedited
Microsoft Edge allows remote attackers to obtain sensitive information from process memory via a crafted web site, aka "Microsoft Edge Information Disclosure 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 confidence

Microsoft Edge contains an information disclosure vulnerability that allows remote attackers to obtain sensitive information from process memory via a crafted website. The vulnerability stems from improper memory handling in Edge's rendering engine, allowing a malicious page to read contents from the browser's memory space that should not be accessible.

MitigationApply the cumulative security update for Microsoft Edge (MS15-112). Until patched, users should avoid visiting untrusted websites and consider using an alternative browser. Enterprise environments should prioritize deploying the MS15-112 update through their patch management systems.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Microsoft Edge is installed
    Open Start menu, search for 'Microsoft Edge' or check C:\Program Files (x86)\Microsoft\Edge\Application\ folder for edge.exe
    Affected if Microsoft Edge browser is present on the system
  2. Check Edge version number
    Launch Microsoft Edge, click Settings (three dots) > Help and feedback > About Microsoft Edge to view the version string
    Affected if Edge version exists and shows as installed
  3. Verify MS15-112 update is installed
    Open Windows Update (Settings > Update & Security > Windows Update), click View update history, filter for 'Security Update for Microsoft Edge (MS15-112)' or check installed updates via Control Panel > Programs > Programs and Features > View installed updates
    Affected if The MS15-112 security update does not appear in the installed updates list
  4. Confirm Edge is the default or commonly used browser
    Check if Edge is set as default browser (Settings > System > Default apps > Web browser) or if users frequently access untrusted websites using Edge
    Affected if Edge is actively used as the primary browser for web browsing

A system is affected if Microsoft Edge is installed and the MS15-112 security update has not been applied, allowing specially crafted websites to read sensitive information from browser process memory.
