CVE-2017-5105
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 · uneditedInsufficient Policy Enforcement in Omnibox in Google Chrome prior to 60.0.3112.78 for Mac, Windows, Linux, and Android allowed a remote attacker to perform domain spoofing via IDN homographs in a crafted domain name.
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 · high confidenceThis vulnerability in Google Chrome's Omnibox (address bar) allowed attackers to perform domain spoofing by using IDN (Internationalized Domain Name) homographs. Attackers could register domains using lookalike Unicode characters (such as Cyrillic letters that visually mimic Latin letters) to deceive users into believing they were visiting legitimate websites.

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.
-
Check installed Google Chrome versionOpen Chrome, go to Menu > Help > About Google Chrome, or navigate to chrome://settings/help, or run `google-chrome --version` from command lineAffected if Version is 60.0.3112.78 or lower (any version up to and including 60.0.3112.78)
-
Verify IDN support is enabled in ChromeNavigate to chrome://settings/privacy and scroll to 'Safe Browsing' section, or check if IDN display is set to show Unicode characters in chrome://settings/languagesAffected if IDN (Internationalized Domain Names) is enabled and Chrome is set to display Unicode characters in the address bar instead of punycode
-
Check Omnibox URL display behaviorVisit a known IDN test site (such as an IDN domain with Cyrillic characters that look like Latin letters) and observe how Chrome displays the URL in the OmniboxAffected if The address bar displays Unicode characters for IDN domains without converting to punycode notation (the prefix 'xn--' should NOT appear for homograph domains)
-
Confirm Chrome is used as the default browserCheck system default browser settings on Windows, macOS, or Linux desktop environmentsAffected if Google Chrome is the primary browser and handles Omnibox URL resolution for the user
A user is affected if they are running Chrome version 60.0.3112.78 or lower with IDN support enabled and Chrome is actively used for web browsing through the Omnibox.

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 dataUpdate Google Chrome to version 60.0.3112.78 or later. Users should also be cautious when visiting websites with non-ASCII characters in domain names and verify SSL certificates.
