Description Tomas Hoger 2017-04-18 12:47:08 UTC 
It was discovered that the FTP client implementation in the Networking component of OpenJDK failed to correctly handle user inputs (e.g. usernames and passwords) containing newline characters.  A remote attacker could possibly use this flaw to manipulate an FTP connection opened by a Java application if it could make it access a specially crafted FTP URL.

Blog posts were published that describe how to use this flaw to open ports on firewalls using active FTP connections:

and sending mails during XML parsing when use of XML external entities is allowed:
