Public exploitNot knownno public code found

The Public Key Pinning (PKP) implementation in Google Chrome before 36.0.1985.143 on Windows, OS X, and Linux, and before 36.0.1985.135 on Android, does not correctly consider the properties of SPDY connections, which allows remote attackers to obtain sensitive information by leveraging the use of multiple domain names.
