Description Tomas Hoger 2017-10-16 21:33:55 UTC
It was found that the FtpClient implementation in the Networking component of OpenJDK did not set connect and read timeouts by default.  A malicious FTP server or a man-in-the-middle attacker could use this flaw to block execution of a Java application connecting to an FTP server.

Comment 2 Tomas Hoger 2017-10-17 19:37:03 UTC
Oracle JDK release notes include the following note regarding this fix:

  core-libs/java.net
  Default timeouts have changed for FTP URL handler

  Timeouts used by the FTP URL protocol handler have been changed from
  infinite to 5 minutes. This will result in an IOException from connect and
  read operations if the FTP server is unresponsive. For example, new
  URL("ftp://example.com").openStream().read(), will fail with
  java.net.SocketTimeoutException in case a connection or reading could not
  be completed within 5 minutes.

  To revert this behaviour to that of previous releases, the following system
  properties may be used, sun.net.client.defaultReadTimeout=0,
  sun.net.client.defaultConnectTimeout=0
