Git uses external 'credential helper' programs to store and retrieve
passwords or other credentials from secure storage provided by the
operating system. Specially crafted URLs that contain an encoded
newline can inject unintended values into the credential helper
protocol stream, causing the credential helper to retrieve the
password for one server for an HTTP request being made to another
server, resulting in credentials for the former being sent to the
latter.");
