Description Tomas Hoger 2014-02-28 09:37:59 UTC 
It was discovered that DatagramSocket implementation in OpenJDK did not perform any packet source address checks for packets received on connected socket.  This could cause an application using DatagramSocket to read a packet from the socket that originates from a different source to the one to which the socket was connected.  This problem is caused by BSD socket API oddity, which returns packets form different source if they were queued before socket was connected.

This issue can make it easier to perform IP spoofing attacks, as it may allow packets to be processed by an application without packets actually having spoofed source address.  It can also lead to limited security manager restrictions bypass.

Comment 2 Florian Weimer 2014-02-28 10:03:44 UTC 
Created attachment 868938 [details]
DatagramSocket-connect-9-untested.patch

Untested patch against OpenJDK 9.  For DatagramSocket, it adds filtering in the socket class itself.  For DatagramChannel, the filter is directly in the native code.
Comment 15 Tomas Hoger 2014-10-14 20:06:48 UTC 
Public now via Oracle Critical Patch Update - October 2014.  Fixed in Oracle Java SE 5.0u75, 6u85, 7u71, and 8u25.

IssueDescription:

It was discovered that the DatagramSocket implementation in OpenJDK failed to perform source address checks for packets received on a connected socket. A remote attacker could use this flaw to have their packets processed as if they were received from the expected source.
