CVE-2014-1584 is a vulnerability of currently unknown severity. The Public Key Pinning (PKP) implementation in Mozilla Firefox before 33.0 skips pinning checks upon an unspecified issuer-verification error, which makes it easier for remote attackers to bypass an intended pinning configuration and spoof a web site via a crafted certificate that leads to presentation of the Untrusted Connection dialog to the user.. EPSS estimates a 2.15% chance of exploitation in the next 30 days.
