A malicious 'Host' header with quoted new lines can inject additional headers and more * glibc's getaddrinfo() ignores new lines and everything after a new line character when the first part looks like a IPv4 address See the following blog post for additional information: <a href="http://blog.blindspotsecurity.com/2016/06/advisory-http-header-injection-in.html">http://blog.blindspotsecurity.com/2016/06/advisory-http-header-injection-in.html</a>
