How to fix?

Upgrade Debian:9 chromium-browser to version 47.0.2526.73-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream chromium-browser package and not the chromium-browser package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The CSPSource::hostMatches function in WebKit/Source/core/frame/csp/CSPSource.cpp in the Content Security Policy (CSP) implementation in Google Chrome before 47.0.2526.73 accepts an x.y hostname as a match for a *.x.y pattern, which might allow remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging a policy that was intended to be specific to subdomains.
