CVE-2017-7153
It allows remote attackers to spoof user-interface information (about whether the entire content is derived from a valid TLS session) via a crafted web site that sends a 401 Unauthorized redirect.
Does this matter?
Lower severity and a low EPSS score (1.92%). Track it; it rarely justifies an emergency change on its own.
