CVE-2014-7948
First published: Thu Jan 22 2015(Updated: )
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.
