The AppCacheUpdateJob::URLFetcher::OnResponseStarted function in content/browser/appcache/appcache_update_job.cc in Google Chrome before 40.0.2214.91 proceeds with AppCache caching for SSL sessions even if there is an X.509 certificate error, which allows man-in-the-middle attackers to spoof HTML5 application content via a crafted certificate.

Security readout for executives and security teams

CVE-2014-7948 is an old Google Chrome flaw where application cache content could still be cached during SSL certificate errors. A network attacker able to intercept traffic could spoof HTML5 application content. The bundle identifies the fix threshold as Chrome 40.0.2214.91 and provides no evidence of current active exploitation. Exposure is mainly legacy browsers: Google Chrome before 40.0.2214.91. The bundle does not identify modern affected products, supported releases, or cloud services as affected. Treat this as a legacy exposure check, not a current emergency, unless old Chrome versions remain in use. Business risk is highest for unmanaged endpoints or embedded systems that missed 2015 browser updates. Mitigation focus: Upgrade Google Chrome to 40.0.2214.91 or later.; Check relevant vendor advisories for distro-packaged browser updates.; Remove unsupported legacy Chrome installations from managed endpoints..
